Comment 8 for bug 41272

It still seems to happen with the new 8.26.18 drivers, although not as often. This is on a fresh install of dapper beta prior to updating anything other than the kernel (2.6.15-25-686). I mistakenly listed the cchtml page above as an "official" ati support channel, it is not. I have however went ahead and started a trouble ticket at the ATI customer service site, and the customer service reps have forwarded this issue to the linux driver team, along with the links to both bugzillas, so hopefully they are well aware of the issue.

In the meantime, I'll try downgrading the kernel if it continues or appears to happen more frequently after updating. Thanks for the tip, Ala!
