Bug#433597: linux-image-2.6.18-4-amd64: Panic with CR2: 0000000000100108 on SATA with software raid-1
Package: linux-image-2.6.18-4-amd64
Version: 2.6.18.dfsg.1-12etch2
Severity: critical
Tags: patch
Justification: breaks the whole system
The problem only happened to me once, and before my last upgrade (with
version 2.6.18.dfsg.1-12), but the changelog does not seem to indicate
that this problem was solved, so I'm opening the bug report anyways.
The machine is running two SATA disks with Raid-1 and LVM. This seems to
be relevant to some of the internet discussions I found, though not all
of them.
I was connected to the machine over SSH (a remote machine) when I got
the following messages:
Message from syslogd@fiasco at Tue Jul 17 22:10:04 2007 ...
fiasco kernel: Oops: 0002 [1] SMP
Message from syslogd@fiasco at Tue Jul 17 22:10:04 2007 ...
fiasco kernel: CR2: 0000000000100108
After that, no user space program would interact with me, but pings
still worked. The machine was rebooted by the hosting company, and now
seem to be functioning again.
Searching the internet I found two discussions that may be relevant. One
is http://lists.openwall.net/linux-kernel/2006/11/04/69, which includes
a patch, and the other is http://lkml.org/lkml/2006/1/4/196. Since the
machine has been up for almost a year before this problem happened, and
from the version numbers and frequencies mentioned by Linus, I believe
that the first link contains the solution to this problem.
Thanks,
Shachar
