--- Comment #18 from Andrey Grodzovsky andrey.grodzovsky@amd.com --- (In reply to dwagner from comment #17)
Interesting observation: If I first switch from the X11 display to the console display (with Alt-F2), and then enter "echo mem >/sys/power/state" on the console, above described crashes upon S3 resume do not occur, and I do not see the "[TTM] Buffer eviction failed" in the kernel log, neither with vm_update_mode=0, nor with vm_update_mode=3.
Switching back to the X11 display after a successful S3 resume to the console also works fine.
What could be the relevant difference here?
Well, there is no acceleration involved when in console mode. So maybe this has something to do with it.
Anyway, i am sidetracked a bit by an internal requirement but once i finish I will get back to this issue especially because I got another report with the same failure as you describe.
