yeah, should be this one, or? : http://www.insanelym...80#entry1876715

can you try if the above kernel works? maybe just comparing size is ok, too.

edit: ehm, sorry, i can look for myself. did it and can confirm this is sinetek's amd test1 kernel.

[rySeeR]

Having problems here too.

My GPU is a hd5770.

Waiting for a fix.

That is the same kernel
When booting up my 10.8.2 today i found something strange.
My dock looked realy weird.
When taking a look at system info , i found this: My GPU wasn't detected as HD6770 anymore!
Right now it says HD5xxx series :'| I cant normally read any article on the internet!
It just glitches.

I really hope to fix this :0

[akimoa]

how unfortunate ...sorry my sarcassm .......


lets all wait and see ....my guess strongens that it is AMD Accel related ......since 48XX seems to run perfect by reports of other users so far ??!!

just a quick question to a 48xx User

is AMDradeonAccelerator Kext loaded aswell on full QE CI ?

tx

[Mad Marcsen]

yeah akimoa, i nearly thought the same.

the radeon hd 4x seems to work the best atm. hd 6x can work and hd 5x is a no go.

if you look into ATI4800Controller.kext and ATIRadeonX2000.kext and compare device strings, you can see that the hd4x series use ATIRadeonX2000 instead of AMDRadeonAccelerator. the thing is: what's the difference between those two? i think only apple or ati could tell us. maybe it's a bug? maybe accelerator uses some ssse3 strings.

is there a chance that a hd 5x could work as 4x? maybe we could try that

[akimoa]

what's the difference between those two?

check the binary file if i knew id tell ya i did all weird experiments X3000 .kext was what the AMD Accel is rite now roughly .... even going back to the stage before like to 10.7.5 when there was no Accel kext ...no chance

[Mad Marcsen]

i did check the binary with otool but as i'm not a programmer, this is mostly weird stuff for me

anyways, since people report problems in lion, too i think apple started to move towards a new acceleratorsystem in lion. the thing is, did they introduce a software bug or is it some strange hardware behaviour that was uncovered with the new software design? what i don't understand is the fact, that sometimes it works for people and sometimes it don't. why? i mean hd 6x all use the same drivers and stuff, but there are certain people wo have no problems. that is why some "hardware bug" comes to mind. or do the radeon's in mac hardware have some special features that normal radeon's don't have?

@akimoa:

you had a little experiment with roms? maybe you could help. i thought i try to inject a rom from a hd4x card with nearly same specs. here is a site with nearly all radeon roms from different vendors. if you wan't to give it a go...

We tried all variants of roms. Akimoa and me injected it via the Bootloader.
Tried to use apple original rom of a 5770, modifing the speed of core and ram and disabling the Powermangement of the original one.
To disable the powermangement and also really helps and make it better but it´s also still not usable.
Reducing the speed also helps but i´m not sure if really the reduce made it better or if it also had something to do with the PM.

@wastez:

wich bootloader did you use and how did you inject?

i'm with chameleon 2.2. tried useatirom=yes and placed the rom in /extra as vendorid_deviceid_subsysid.rom. the bootloader loads the rom but immediately halts the system. tried with the original rom from my card and it's the same...

so, am i missing something?

[akimoa]

http://www.insanelym...20#entry1881519

u missed something ! yes

[Mad Marcsen]

@akimoa:

d'oh

wrong chameleon

thank you

I was just wondering... Do the issues everyone's having with ATI graphics resemble the issues I sometimes have with this Intel Core i3-2350m, Intel HD Graphics 3000, and stock mach_kernel?

yeah looks the same.
however those green distorted fields are blue at my pc.

Pretty much like that on my machine too. The artifacts are a bit different, but the glitch itself seems to be same.

[theconnactic]

Thank you very much for this, Instant Idiot!

I know it's an ATI topic, but those are exactly the same greenish glitches i have with my nVidia G210. The difference is that with my nVidia, the glitches cover the screen all over (not intended to rhyme) rendering the system unusable (sometimes, if i was using SL before starting ML, i get a pixel dump of my previous SL session mixed with the glitches).

Best regards!

[instant idiot]

Hmm, very interesting... With the Intel HD Graphics 3000, the little green squares are always present to some extent, but only rarely do they render the system unusable. It all depends on what happens when the login screen appears; if it's badly covered in artefacts, then I have to reboot to avoid total corruption, but if there are few or no artefacts, then it will be fine for the rest of that boot. There is absolutely no pattern, but the AppleIntelSNBGraphicsFB.kext from 10.7.0 works way better (higher percentage of usable boots) than the 10.7.5 one.

There is a fix though...well "fix" it can help and does a great job, but sometimes it is still prevailent. You can find it in the Probook installer on t0nymaccc. I was thinking it might help you ATI kids, but I dont have ATI so I cant test.

[instant idiot]

You mean the patched AppleIntelSNBGraphicsFB? It has absolutely no effect against the green rectangles on my ProBook.

After reading about 10.8.2 and the issues about glitches is not only thing that appears. There are 2 versions of osx 10.8.2 ..For some reasons the new macbook pro and mac mini are having also issues with it.
From not installing to video - output problems . The kernel is not the major problem ,it's stable enough to run for hours . I think there is a problem in the OS itself regarding to official macs who appears to have the same or simular problems . My guess is that it will be repaired in 10.8.3 .Or is that to simple ?
