Jun 25, 2011 3:52 PM in response to Eminemdrdre00by Matthew Yohe,Which video card do you have? Mine is the 2600 and I have not had an issue yet. (yet!)

Jun 25, 2011 5:04 PM in response to DazzaGby TK111,People, please, you have to be very specific about what you've done otherwise it's like a bunch of old ladies ******** and no help to anyone else. To wit:
OSX 10.6.7, 24" 2.8GHz Core2Duo, ATI Pro2600, iMac8,1:
I was having 10 freezes requiring hard restarts every month for a year, Apple store could not duplicate, no help.
Discovered this thread, applied the kext solution in May and had no freezes for a month. Two days ago I backed up (using SuperDuper!) and applied the 10.6.8 update with the kext solution in place using the 474.2 MB download (NOT the combo update or the Software Update version).
Since then, no freezes yet. Everything seems fine. I'm hopeful. Still glad to hear about the kernel panic thing, though, and will watch out for it. But take that stuff with a grain of salt.

Jun 25, 2011 8:19 PM in response to TK111by TK111,Unbelievable. The next time I woke my iMac from sleep (2 hours after I wrote the post above) I got a freeze with grey screen. Hard restart. I'm going back to my backup of 10.6.7 with kext fixes and not upgrading this machine until there is some evidence that Lion works.

Jun 25, 2011 9:59 PM in response to Matthew Yoheby Eminemdrdre00,I've got a 2008 20" iMac with the ATI Radeon HD 2600 Pro. I've been having issues with freezing ever since upgrading to 10.6.3+

Jun 26, 2011 2:11 AM in response to Matthew Yoheby Tardigrada,ATI Radeon HD 2600 Pro. Without the 10.6.2 kexts my iMac freezes about every two days once. Did not update to 10.6.8. because of the problems described. Thus locked in 10.6.7.
Looks like the NVIDIA GeForce 8800 GS 512MB (PCI Express) Video Card fits into my 24" iMac. Unfortunately that old card costs a bunch of money. And also I don't know if it really fixes the problem.

Jun 26, 2011 2:50 AM in response to DazzaGby morpho,What's more disturbing is the fact that 10.6.8 comes with *A LOT* of security fixes, most of them addressing serious vulnerabilities.
So we're stuck with two possible scenarios:
- a secure but unstable (and thus unusable) machine;
- a stable but extremely insecure machine.
Way to go, Apple...

Jun 26, 2011 7:22 AM in response to morphoby TK111,Would you really say "extremely insecure?" That seems a little overboard. 10.6.7 is no less secure than it was before, which I thought was pretty good. Never had a problem that way. Still, this ***** badly.

Multiple arbitrary code execution vulnerabilities (ATS, QuickTime, ColorSync and so on) with "safe" files as exploit vectors IMHO qualify a system running 10.6.7 or lower for such a definition.
But we're (mostly) off-topic, bottomline is that we're forced to run a lower OS version with known vulnerabilities (and known bugs for those of us who are on IPv6-enabled networks) because Apple refuses to acknowledge that this is a **** software regression and not an hardware fault.

Jun 26, 2011 1:25 PM in response to DazzaGby jnik,20inch iMac 8.1; 2.66GHz; ATI Radeon HD 2600 Pro. 10.6.7.
As per my earlier post, my freezes started after the upgrade to 10.6.3. They stopped after an SMC re-set. Not had one for 3 weeks. Then they came back - don't know why. Frequency: 2/day - 1per3days and anything in between. Did another SMC reset and coming up to two weeks without a freeze. Go figure, i'm sure they'll come back, but at least it's peaceful for now. Maybe would help someone to know.
Have not taken 10.6.8 yet, will do soon.
The whole point of switching to a Mac was the few HW configurations that were VERIFIED to WORK. After this disaster, I may just as well go back to Windows... And we're just too small a fraction of Jobs' sales for them to care about us.

Jun 26, 2011 1:32 PM in response to DazzaGby Tazthed,This is day 3 with 10.6.8 and stil NO freezing even though I use my mac every day (24 inch iMac ATI Radeon HD 2600).
Like I wrote earlier, I did this:
First, I was on 10.6.7 using the fix with the old kext files from 10.6.2. Then I updated to 10.6.8 using software update... I did not touch the kext files in 10.6.8.
Maybe I am just lucky ?

Jun 26, 2011 2:22 PM in response to Tazthedby spokes46,I installed 10.6.7 when it came out and had no freezes for 2 weeks, then they came big time. That's when I finally did the kext thing. No issues since. I wish you well with 6.8, but don't be surprised if it rears its ugly head.
-
Jun 26, 2011 7:02 PM in response to Tazthedby Eminemdrdre00,@Tazthed you're lucky for now, but it'll lock up eventually. When I first upgraded to 10.6.7 (without the kext fix) I went a few days before it finally froze. I have the same graphics card as you in my 20" iMac from 2008 and it froze up for me on day 1. As mentioned, the 10.6.2 kext fix does NOT work on 10.6.8

Jun 27, 2011 9:05 PM in response to DazzaGby richardernie,10.6.8 is horrible. I've had these weird graphic problems and crashes ever since it was released. I've never had to hard reboot my machine so many times! Come on Apple...I expect better from you. Anyone got a good fix to this?
-
Jun 29, 2011 7:13 AM in response to DazzaGby Tazthed,Okay, so today my iMac froze on 10.6.8!
Back to 10.6.7 again.....

Jun 29, 2011 2:45 PM in response to DazzaGby Harkaitz,Hey Guys!
I´m now writing from my imac 8.1 with OSX 10.6.8 and the 10.6.2 ATI Kexts for my radeon 2600.
How?
Easy, I remembered that when I installed Lion and tried the kexts, the Lion kernel was working on 64 bits.
With Snow Leopard working on 32bit I got (like all of you) a nice Kernel Panic. Here how to make them work:
Go back to 10.6.7 reinstalling or doing like you want.
Apply 10.6.8 combo update.
run console and type cd /Library/Preferences/SystemConfiguration/
type sudo nano com.apple.Boot.plist
here you will be asked for your admin password
modify the line <string></string> to <string>arch=x86_64</string> (jus add that arch=x_64)
press control+o
press control+x
reboot
apply the 10.6.2 kexts
reboot
On 64bit mode the 10.6.2 Kexts work like a charm.
I hope this will help you.
Good night from Donostia! (Spain)
