Bug#685608: linux-image-3.2.0-3-amd64: unable to handle kernel paging request __d_shrink
Package: linux-image-3.2.0-3-amd64
Version: 3.2.0
Severity: important
Dear Maintainer,
I got following kernel oops when running stock debian kernel
linux-image-3.2.0-3-amd64: 3.2.23-1. I have seen oops once before but it is
very infrequent making reproducing practically impossible. The oops
happened when there was no major disk activity in system except
log rotation had kicked in a moment earlier.
System is:
64bit Mobile Core i5
Intel Ironlake graphics
AMD Radeon 5650 (evergreen)
dm-crypt encrypted ext4 and swap paritions in rotating disk.
I know that there is reports about memory problems with both of my
graphics drivers. I have also seen 3 times complete deadlock which might
kernel oops that failed to do modesetting back to console. Or it could
be genuine deadlock. But I think it is more likely that oops handling
path has some deadlock because many oops handling paths are trying to
take locks even tough those locks might be already held before oops.
Also suspended radeon doesn't tell hdmi audio or remember
that hardware is suspended. That leads to a few tries to access hardware
that lead to wait for timeout inside locks. But I haven't noticed
any more issues caused by those bugs.
But I was actually surprised that oops were stored in syslog after
reboot so I decided to report it a bit later. I'm now running debian
kernel with kernel memory and lock debugging enabled.
Only report that I could find online with anything similar is
http://lists.opensuse.org/opensuse/2012-03/msg00481.html but that is
coming from btrfs. But I'm hoping that if I report this there could be
someone else providing more information about this infrequent problem.
I don't know why every entry is twice in my syslog. I didn't have time
to investigate that. But there was only one oops that is twice in the log.
Crash happens in "mov %rcx,0x8(%rdx)" but my config and compiler
generates completely different code for the function. So I can't use
objdump to disassemble the function and match to this report. I don't
know how to disassemble vmlinuz.
