Latest working kernel version: 2.6.27.18 works perfectly. Earliest failing kernel version: 2.6.28.7 cashes sometimes.

Problem Description: Sometimes when I execute a suspend to ram the system freezes completely. Steps to reproduce:
Created attachment 20451 [details] dmesg output
The dmesg-output above is from a normal booted system. The oops is not visible in this attachment :-(
Created attachment 20452 [details] Part of the kernel oops.
Hi, Martin From the problem description it can work well on the 2.6.27.18 kernel but it fails on the 2.6.28.7. It seems that this is a regression. Will you please use git-bisect to identify the commit which causes the regression? Thanks.
how about boot option 'nohz=off'
ping Martin.
Sorry for the late response. I've tested now the latest stable kernel 2.6.28.8. Did several suspend to ram/resume cycles. Also one suspend to disk. The kernel crashes seem to be gone now. I think the bug can be closed :-) > http://bugzilla.kernel.org/show_bug.cgi?id=12840 > > > > > > ------- Comment #6 from rui.zhang@intel.com 2009-03-23 00:56 ------- > ping Martin. > >
