Bug#576274: I finally have a meaningful log to report
Hi there,
I am currently running linux-image-2.6.32-5-686 and I checked /var/log/kern.log instead of /var/log/Xorg.0.log for clues after another "white screen" (I am pretty tired of testing suspend, because the white screen always happens when I am right in the middle of work), and here it is. Finally some meaningful log output to back up the bug report:
May 27 09:15:29 voltaire kernel: [16440.384972] render error detected, EIR: 0x00000010
May 27 09:15:29 voltaire kernel: [16440.384979] page table error

May 27 09:15:29 voltaire kernel: [16440.385002] PGTBL_ER: 0x00000010
For almost an hour nothing is in there before that time and nothing happens after that until I shut the machine down.
Thx,
Malte
Problem remains the same, computer is fine after normal boot, but the screen goes white after pm-suspend, wake up, and then some time after that.
Here is some log output from the wakeup about an hour earlier:

and then another couple of lines concerning the i915:
