Hi!
On my Thinkpad T500 with Debian-compiled kernel 2.6.35~rc6-1~experimental.1, I still get OOpses on suspend.
Did it happen with 2.6.34 or previous kernels?
Yes, the suspend/resume also failed with 2.6.34, although I only tried suspending from X, which almost always leads to a blank screen, so I can't say whether the symptoms are the same. Of course I can test that if you think this is useful. However, rc5 and rc6 contained a fix for i915 related to suspend/resume, which might hide this remaining problem. So it might not be particularly useful to test 2.6.34.
As far as I remember, KMS always led to problems related to suspend/resume, but the both the highly patched Debian Kernel 2.6.32-18 (Debian version) and 2.6.35-rc6 fail very often on suspend. I'd like to avoid testing earlier 2.6.32 kernels, because some of them even cause file system corruption on suspend. (If really required, I could set up a small test partition, and hope that the filesystem corruption was no arbitrary write on the disk, but only on the partition.)
The last time I had no problems with suspend/resume was with some kernel 2.6.29 version, which of course used User Mode Setting. I actually didn't cold-boot my notebook for 180 days back then.
Thanks for the reply, but please keep the CC list when replying next time.
