Description akwatts 2011-07-22 03:41:58 UTC 
Hi,

Just got an OOPS after resume from hibernation on 2.6.39.3 (echo disk > /sys/power/state). So far it's happened only once (out of the 4 or 5 times I've hibernated 2.6.39.3).

I was able to rescue the following OOPS fragment before the system froze entirely. I hope it is enough to give clues about what went wrong.

Comment 1 Len Brown 2011-08-02 02:58:22 UTC 
what machine is this?

is it still failing 1/5 times in 2.6.39.stable?
this bug is marked as a regression --
did it resume consistently over many tries in 2.6.38?
Comment 2 Zhang Rui 2012-01-18 05:26:07 UTC 
It's great that the kernel bugzilla is back.

Can you please verify if the problem still exists in the latest upstream
kernel?
Comment 3 Zhang Rui 2012-05-24 08:01:40 UTC 
bug closed as there is no response from the bug reporter.
please feel free to reopen it if the problem still exists in the latest upstream kernel.
