Jul 28, 2011 6:13 AM in response to Chris J.by swmaster,Chris,
could you please post the output of the following command (kextstat | grep ATI) to this thread just to check what version of kexts are you running. it should look something like this:
cy-bear:~ swm$ kextstat | grep ATI
76 2 0x12d1000 0x32000 0x31000 com.apple.kext.ATISupport (6.2.6) <75 14 13 7 5 4 3 1>
77 0 0x1303000 0x23000 0x22000 com.apple.kext.ATI1600Controller (6.2.6) <76 75 14 13 5 4 3 1>
92 0 0x948000 0x5b000 0x5a000 com.apple.ATIRadeonX1000 (6.2.6) <78 75 13 7 6 5 4 3 1>
110 0 0x1326000 0x13000 0x12000 com.apple.kext.ATIFramebuffer (6.2.6) <76 75 14 13 7 5 4 3 1>
btw, that's a white 20" intel imac4,1 running stock 10.6.7 w/o any side effects. i will replace the core duo w/ a core2duo soon to get it lion-aware.
my guess is that you still use the original lion drivers from the kext cache.
my other 20" alu imac7,1/2400XT still runs the untouched lion pretty stable, since the last freeze happened last friday.

Jul 28, 2011 7:20 AM in response to Chris J.by johnckendall,Dude, where did you get 6.0.6 version from? Any way you can make those available?
And why does the System Info app show 7.2.9 but that command shows 7.0.2 ?

Jul 28, 2011 4:26 PM in response to Chris J.by swmaster,i can confirm, you really run the old ones.
this is what i will try right now. i've got them 10.6.2 kexts at hand :-)
my imac7,1 freezed 4 times today, had to reboot it from ssh. once i wasn't even able to click on my head to log in after restart. got GPU debug info all the time to the log.

Jul 28, 2011 6:58 PM in response to swmasterby Chris J.,Yea they are old ones but the work. Good luck to you on it. Keep us updated.

Just installed on an imac 7.1 with 2600pro and working with 10.6.2 Kexts.
There was a user having problems with the patch but on my 7.1 never failed (even on lion betas).
That user was me! Maybe the ATI 2600 works in Lion but the 2400 is still busted? Can anyone confirm this? It would be super awesome if everything is fixed except for my particular machine with my particular graphics card. Of course by super awesome I mean terrible.

Jul 29, 2011 12:19 AM in response to buminaby swmaster,Bumina,
mine is imac7,1 with HD2400xt.
i installed the good old 10.6.2 drivers 8 hours ago.
they work - that means, OSX was able to load them despite the fact they are originally meant for 10.6.

there is one thing i missed, i forgot to replace the ATIRadeonX2000.kext with the old version, so as you see this one is from lion (ver. 7.0.2).
we'll see how it performs. yesterday evening i had 4 gpu freezes in 2 hours w/ the original Lion drivers. once i wasn't able to get to press enter after i typed in my password on the login screen.
well, at that point my mind just blown up.
NOTE TO EVERYONE:
save the original lion kexts to a safe location for the case anything could go wrong.
if you replace the lion ones w/ the 10.6.2 kexts, be sure to remove all extended attributes from them, or OSX will ignore them and you will be sitting next to a blacked out imac. and make sure they are owned by root:wheel
it goes like this:
$ sudo sh
# cd /System/Libraries/Extensions
# chown -R root:wheel ATI*
# xattr -dr ATI*
it is done in a fraction of seconds.
then just wait for 2-3 minutes for kexthelper to automatically rebuild the kernelcaches in the background.

Jul 29, 2011 1:48 AM in response to swmasterby kremik,Hello,
I have a 7,1 iMac with with ATI2400. I had many freezes in Snow Leopard so I did the kext replace and used 10.6.7 with 10.6.2 kexts without any problem. Then I decided to upgrade to 10.6.8 and try not to replace kexts. I seemed as OK, I didn't have any freeze for 2 days. But after two days I've got a freeze 2x - 3x per day. I didn't do 10.6.2 replace and I waited for Lion. The scenario with Lion was the same - no freeze for 2 days and then 2 or 3 per day (well Lion saves the state, so after restart I didn't loose all my work).
Yesterday I replaced kexts in Lion with 10.6.2 ones and it seems to work without any problem. The output of kextstat | grep ATI is the same as swmaster posted. I just wonder if it is required to replace com.apple.ATIRadeonX2000 (7.0.2) with older version too?
According to the previous experience it's to early to judge if the kext replace works or not. I will let you know.
