Comment 19 for bug 456902

I tried passing nomodeset to the kernel on boot to disable KMS, but still get identical freezes. I will post a tarball of debugging info as soon as I can. (Desktop effects have been off the whole time I've seen this bug.)

Interestingly, while 1280x1024 resolution is not available anymore (and was available under jaunty!), it becomes available if I pass nomodeset to the kernel. Same freezes, though.

I also tried the xorg-edgers ppa with both the stock karmic kernel and with the newest mainline kernel from kernel-ppa. With xorg-edgers and the stock karmic kernel, I get identical freezes. With the newest mainline kernel from kernel-ppa and xorg-edgers, I get a freeze that behaves somewhat differently and seems to happen more frequently - plus there are i915 errors printed on the first virtual console about rendering errors with this kernel/xorg combination. If I have a chance I can submit tarballs of debugging info for all combinations of kernel/xorg I've tried, but I'm unsure that it's the same bug.

I am open to any other advice or debugging techniques no matter how off-the-wall.
