Can you try to revert commit 4b4f7280d7fd1feeff134c2cf2db32fd583b6c29 and retest, please?

4b4f7280d7fd1feeff134c2cf2db32fd583b6c29 isn't easily revertable.

anyway bisecting and currently on second try 3ea9eed49346eb80f17f1c6539c47dc508be1173 is good as expected,
will post bisect result soonest.

Reverts for me 100% cleanly.  Can you please verify that you're testing -rc9 without any additional patches?

hmm bisecting on plain linux-2.6 linus branch, 537388bb6563bfde7c0307b95ecc1f7a1ae39b02 turned out to be good that includes 4b4f7280d7fd1feeff134c2cf2db32fd583b6c29.

not sure if i reproduced correctly immediately launching suspend to ram after gdm login. will recheck plain 2.6.26-rc9 on desktop usage soonest.
Comment 6 Rafael J. Wysocki 2008-07-12 14:03:52 UTC

Comment 8 Rafael J. Wysocki 2008-07-13 11:13:30 UTC
The solution appears to be not to use the s3_bios user space resume quirk related to graphics.

Still, we need to verify if the quirk is generally broken by commit 4b4f7280d7fd1feeff134c2cf2db32fd583b6c29.

Possible fix

Please test out this patch.
Comment 10 maximilian attems 2008-07-14 08:13:53 UTC
Back, will continue bisect later today and test proposed patch.

could verify that 2.6.26 is affected.
Comment 11 Bruno Randolf 2008-07-14 08:34:03 UTC
got the same problem on a X61 thinkpad and kernel 2.6.26. peter anvin's patch solves the problem for me!
