how are u guys getting sleep?

Is there a Sleepenabler for 10.7?

Mine just won't wake up again.

maybe you have the same problem as we all! First, in snow it works fine ? Always in snow... you have to use a sleepenabler.kext?

 

you can maybe try to overwrite the AppleRTC.kext in S/L/E on lion with the one from Snow leopard located in S/L/E!

Hope you resolve,Good luck!

Thank you for your answer! Yes, I always had to use Sleepenabler to get Sleep (worked fine from 10.6.0 to 10.6.7)

So you guys always had sleep without Sleepenabler?? Hmmm I might need to do some research....

If you make the proper edits to your dsdt.aml you can get rid of it! I don't even know if someone has been created a sleepenabler for lion.

There are a lot of thread about it, good work!

...kinda boggles my mind people still use sleepenabler. Let's just fix our dsdts...? :)

Situation remains the same with Build 11A459e, solution same as per JUN Ho. Only IOPMrootDomain console msg with 'SystemWillSleep' is gone.

Same as rayap, replacing RTC with Snow version is working with DP3 ok. Now I have KP with AppleIntelCPUPowerManagement... =(

Err... As I said, if we want to find solution for this one, then first we need to check DSDT that is working 100%

 

If someone could leave here such a DSDT, that would be really nice... :)

Here's a DSDT from ASUS P5G41T-M LX & E8400 Core2Duo CPU. Sleep works without AppleRTC replacement. Check it out.

 

Download here:

Honestly I believe the sleep issue is related to the number of CPU cores. Anyone with a dual-core processor experiencing these cmos reset issues on wake?

Foxconn P35A with Core2Duo E4500 is my configuration and I can confirm that my CPU is still E4500... So I'm not sure about your theory… It seems like that there is no any pattern here and that all this happens totally random, in which of course I still don’t want to believe...

 

Anyway, thanks for DSDT, I’ll check it ASAP…

Sleep works fine for me without AppleRTC replacement. It's just the CMOS reset I suffer from.

Yes.

 

Gigabyte GA-EP45-DS3L, Core2Duo E7300 (*depends if the signature is updated)

My signature is up to date, so I can confirm the E7300.

We're talking about the same sleep issue then, right?

 

The system will go into what seems like S3 sleep, but upon wake it restarts your computer and resets the cmos. This is the issue you're experiencing, correct?

 

 

Thanks for the feedback blackosx!

I have the same issue if I don't replace AppleRTC! Sleep works fine, but upon restart, CMOS resets :P

OK. I found solution, however I’m not sure will it work on all motherboards, because the code in this DSDT for ASUS P5G41T-M LX, is pretty much different than the code that I have for my motherboard P35A. So it seems to me like that there are two possible and perhaps a bit different solutions in the code, which of course depends from the type of BIOS and motherboard.

 

[edit]

 

It seems that this doesn't work...

Mine looks like the first one, but the IRQNoFlags fix doesn't work. Still getting CMOS resets when I sleep my computer ^^

No. My system will sleep and wake fine and stays perfectly useable until I restart or shutdown. That's when I suffer the CMOS error.

 

So, as you can see, it seems that missing IRQ piece of code is the fix for the actual CMOS reset problem…

Has this actually fixed the CMOS reset issue for you?

Because like MaLd0n, I've already tested with IRQ's in Device (RTC) without any success.

 

The obvious thing here is that the code for Device (RTC) is very differnet... It content lines which doesn’t exists in my case...

Here's a sample from my original Gigabyte DSDT extracted from acpidump. Does this look familiar when compared to the one from ASUS P5G41T-M LX ?..

Device (RTC)
               {
                   Name (_HID, EisaId ("PNP0B00"))
                   Name (ATT0, ResourceTemplate ()
                   {
                       IO (Decode16,
                           0x0070,             // Range Minimum
                           0x0070,             // Range Maximum
                           0x00,               // Alignment
                           0x04,               // Length
                           )
                       IRQNoFlags ()
                           {8}
                   })
                   Name (ATT1, ResourceTemplate ()
                   {
                       IO (Decode16,
                           0x0070,             // Range Minimum
                           0x0070,             // Range Maximum
                           0x00,               // Alignment
                           0x04,               // Length
                           )
                   })
                   Method (_CRS, 0, NotSerialized)
                   {
                       If (LGreaterEqual (OSFX, 0x03))
                       {
                           If (HPTF)
                           {
                               Return (ATT1)
                           }
                           Else
                           {
                               Return (ATT0)
                           }
                       }
                       Else
                       {
                           Return (ATT0)
                       }
                   }
               }

Most of this was stripped out from the DSDT I use now because I can see that the _CRS code logic returns either ATT1 or ATT0 which are both the same. That's also why ATT1 has been stripped.

 

Having said all this, I will test again just to double check things but keep looking as the answer is there somewhere. :)

Are people here still seeing this: "Only one ram bank..." message in kernel.log?

 

Try this:

				Device (RTC)
			{
				Name (_HID, EisaId ("PNP0B00"))
				Name (_CRS, ResourceTemplate ()
				{
					IO (Decode16,
						0x0070,			 // Range Minimum
						0x0070,			 // Range Maximum
						0x01,			   // Alignment
						0x08,			   // Length
						)
					IRQNoFlags ()
						{8}
				})
			}

I use 0x08 here since there are actually 8 RTC registers, as combo of a data and index register.

Hi DHP.

 

I'm at work now so I can't check my kernel log for that message, but I think I've previously tried the Device (RTC) section you posted purely because that's exactly what my iMac11,3 uses... though looking at it again now, the iMac version doesn't have the IRQ part so now I'm not sure what I tried.. That'll teach me not to have written down my various attempts here :(

 

I've got the Intel datasheet 319973.pdf for ICH10 here which I will look at again for ideas, so I guess I have more reading to do.. I'll look more in to the registers.

 

I currently have in my DSDT for HPET and RTC:

 Device (HPET)
               {
                   Name (_HID, EisaId ("PNP0103"))
                   Name (_STA, 0x0F)
                   Name (_CRS, ResourceTemplate ()
                   {
                       IRQNoFlags ()
                           {0}
                       IRQNoFlags ()
                           {8}
                       Memory32Fixed (ReadWrite,
                           0xFED00000,         // Address Base
                           0x00000400,         // Address Length
                           )
                   })
               }

               Device (RTC)
               {
                   Name (_HID, EisaId ("PNP0B00"))
                   Name (_CRS, ResourceTemplate ()
                   {
                       IO (Decode16, 0x0070, 0x0070, 0x00, 0x02, )
                   })
               }

 

For interrupts, the Intel datasheet reads

5.11.2 Interrupts

The real-time clock interrupt is internally routed within the ICH10 both to the I/O APIC and the 8259. It is mapped to interrupt vector 8. This interrupt does not leave the ICH10, nor is it shared with any other interrupt. IRQ8# from the SERIRQ stream is ignored. However, the High Performance Event Timers can also be mapped to IRQ8#; in this case, the RTC interrupt is blocked.

So I interpret this that I don't need the IRQ in Device (RTC) as in your section - would I be right with that assumption?

Because like MaLd0n, I've already tested with IRQ's in Device (RTC) without any success.

Yes. It's working in my case and I don't have any more CMOS reset. I make twice sleep/wake/restart operation from Lion and everything was been fine after that... (Lion updated to 11A459e)

 

Hmm... well I was suspected that this little fix will not working on all motherboards, but I didn't expected this...

So I guess at least that it pointing in good direction... :(

 

[edit]

 

Well, this also doesn’t stand anymore… It was worked a couple of times and after I was saw here that IRQ piece of code was helped non of you I was decided to switch one more time AppleRTC.kext except this time I was extracted it directly from latest update, just to be sure that everything is fine… However, after that rollback I was become aware that it actually doesn’t work again to me too!!! Strange, because I did rollback on original AppleRTC.kext, and I had 3 or 4 times CMOS reset before I made those changes in DSDT. After those changes I was successfully restarted my computer 3 times… Tomorrow I was made once more rollback just to be sure that everything is fine, but after that I was become aware that it doesn’t work again…

 

So this isn’t solution, but obviously big fail… Sorry for this guys…

 

I’m confused now what really happens… I need to make more tests to figure what’s going on… Damn...

Thanks for the confirmation. In that case well done, you seem to have cracked it!! :(

For me, I need to test this when I get back to my hack. As I can't remember exactly what I've tried.

Even without sleep, length 0x04 or 0x08 causes CMOS resets for me.

And, 'kernel: RTC: Only single RAM bank (128 bytes)' msg for length 0x02 only but resets CMOS after sleep with AppleRTC v1.4

 

P.S. AppleRTCv1.4 causes CMOS Resets After Sleep in SnowLeopard too!
