Hi, that's not us, but perhaps your BIOS firmware. We do not create anything alike, and code search gives no findings in our repositories aside EDK II copy, which part we do not use (https://github.com/search?q=org%3Aacidanthera+MonotonicCounter&type=Code).

No, I don't think that it is intentional. But then again I never see this problem before using clvoer grub2 etc. I checked the code before I posted and I didn't see anything. Only in Datahub.c was mention of monotonic. But then again edk2 does some strange things, so I will check there.

Hi, I have weird issue since catalina. My bios suddenly becomes a black screen I cant enter my bios settigs. The problem is in both opencore and clover. In clover every boot was causing black screen. I succesfully managed to switch opencore and its nvram reset option fixed that black screen issue but after few reboots I'm getting black screen error again when error occurs my bios also removes opencore from boot selection part. Only way to access it again reflashing my nvram with a bios tool. 

I have never experianced that kind of issue before on mojave. 

Device: Asus FX553VD/GL553VD i-7700hq. 

Here is my opencore files.

Has anyone had trouble with SATA since moving to Catalina? I get an immediate panic and restart at the progress bar.

 

I can boot with ACHI enabled in bios. However, I as soon as I enable any one of the 6 ports (with or without a drive connected) I get the panic/reboot.

 

Note: the SATA Rename SSDT has no effect here. Please excuse if this has been addressed.

Fix HPET in ACPI. (Add IRQ in HPET)

For example:

 

Thank you very much for your help! I added an IRQ in that IRQNoFlags to:

 {0,8,11,15}

in my case and it worked without blocking the kext. Thank you so much!

@DanielMac HPET can be disabled by writing to HPTE = 0

Thank you for that information, but I don't understand the implications of disabling HPET. Do I need HPET for something? Why does it take up 4 IRQs?

Hi @vit9696

Hi @Download-Fritz

I know it is a low priority for your OpenCore's bootloader project but I would like to ask you

AMD TRX40 user of new threadripper3 have the same initial problem (memmap error or an instant reboot if DevirtualizeMMIO is used) after ++++++++endseed stage

this happens with different motherboard and different bios settings and also using all Aptio memory EFI driver available 

 

Do you think this problem could be superated with a new aptiomemory efi driver? Or it is unrelated in your experience?

 

Thank you in advance

 

[mhaeuser]

We have no technical information on the matter and we neither have the hardware, nor time or ambition to investigate. If someone researches and describes the issue technically(!) (what causes the bug, not "it reboots when blah blah"), we will merge the fix.

Please do not tag for no reason.

[Guest]

Ok sorry for bothering you with my tag

But i see people open issue on openCore GitHub and i think people do not know "what causes the bug" otherwise we could be more useful to debug

thank you for your time

if the processor supports XCPM (Xnu CPU Power Management), HPET is not needed.

@fabiosun try DevirtualiseMmio+MmioWhitelist

[mhaeuser]

@hardcorehenry And what addresses is he supposed to add? It's very unlikely DevirtualiseMmio causes the issue, and if so, it'd need a lot of trial and error or serial kernel debugging to get the KP

thank you but all things found on public forums  have been tested with the same result from different users with different motherboard

could you help for a serious debugging?

 

[hardcorehenry]

What I meant, I wasn’t able to boot with DevirtualiseMmio quirk alone(KP), MmioWhitelist also had to be enabled. I don’t need that quirk, just wanted try it, out of curiosity. Addresses can be extracted from DarwinDumper(Memory), if you are able to boot with clover.  But no sadly I can’t provide help for serious debugging.

Addresses undertake from OpenCore log.

[mhaeuser]

If you add all addresses to the whitelist, the quirk does nothing at all. I think you must have seen a KP when it was on without the whitelist? @hardcorehenry

[Andrey1970]

At first to add all addresses, but then to delete not necessary addresses. What addresses to leave, it is necessary to define experimentally.

Could you define better this?

Then,  how to debug seriously this new AMD cpu/bios  problem?

It won't solve your problem. Don't use quirk DevirtualiseMmio.

Yes I know , i have tested all advice see also in opencore GitHub, also calculate my free slide but Always same problem

I would like to do a serious debugging as DF said above..if you can address me i will try

Thank you

Leaving this here for anyone who's got a well zipped up EFI and good knowledge of what needs to happen to have a good system but cant boot into Catalina.

 

I discovered I couldn't get in if I had any SATA ports enabled in bios. I disabled them and scoped out everything. All seemed well.

 

After a day or so I found adding AppleAHCIPortHotplug.kext prevented OC from having a panic. Thats all!

Do you guys know how to create your own "SSDT-EHCx_OFF"?

Currently I don't have "SSDT-EHCx_OFF" and system still bootable. 

it doesn't have usbinjectall.kext and usbports.kext.

should I create it? 

 

I have z87 mobo, i5-4570, RX580

You have good enough mobo to live without all them.

Unbelievable. I also made a SSDT-PLUG from SSDTTime.

Not sure if i need this or not?
