Kernel Bug Tracker – Bug 32222
Possible kernel panic after resume from s2disk
Last modified: 2011-04-16 20:07:55 UTC
After kernel update suspend to disk works normal, but after resuming system is unresponsive. Resume process shows on a tty, but when it hits 100% and screen clears kernel possibly crashes (cursor stays but not blinks, no any response on SysRq keys) - seems to be kernel panic occured.
Kernels prior to 126.96.36.199 works well (current - 2.6.38).
Same behavior on latest stable longterm (188.8.131.52).
Is the problem 100% reproducible?
I'm experiencing the same issue here. Suspend to disk works fine for kernel versions before 184.108.40.206.
Steps to reproduce: echo disk > /sys/power/state, power on again, data is loading from swap partition (3GB, 2GB RAM), 100% loaded, screen goes black (everything's still fine), screen stays black, the two rightmost leds on my keyboard start blinking. No response to SysRq keys. No traces in the logfiles.
Out of three suspend->wake up cycles I've had this problem every time.
Can you check if reverting this commit helps:
