Description vaibhav 2010-09-20 17:37:40 UTC

 I am using kernel 2.6.34-rc4 directly taken from kernel.org. After suspend to ram if I leave it for few hours and resume then kernel panic happens (screen of death). If I suspend and resume immediately then it works fine. I am attaching hand copied text which was displayed at panic.

Its a dual core intel machine. Let me know what other information is needed from my side.
I had sent a mail to lkml. Response from lkml :

"I think that sta_addba_resp_timer_expired() is a red herring.  More likely the
problem is related to cpuidle.  Apparently, the suspend-resume cycle causes
the ACPI cpuidle driver to malfunction." - Rafael J. Wysocki

Have you tried to put acpi_sleep=nonvs into the kernel command line?

Panic occurred even without suspend/resume and details looked similar to one I have already reported. So I think it is not really suspend/resume issue. It is hard to reproduce this bug, I have no idea when and what would trigger the panic.

Is this still and issue with 2.6.37?
