Summary: ooops report 2.4.20-xfs-CVS-2003-02-21_06:00_UTC
Product: Linux XFS
Version: Current
Platform: IA32
OS/Version: Linux
Status: NEW
Severity: critical
Priority: High
Component: XFS kernel code
AssignedTo: xfs-master@xxxxxxxxxxx
ReportedBy: jeffrey.hundstad@xxxxxxxx
Hello,
We had a machine hang on us twice since upgrading from 2.4.18-xfs. It ran for
months without any problems. We upgraded to 2.4.20-xfs-CVS-2003-02-21_06:00_UTC
and patched it for the ptrace vurnerablility. When the machine hangs it has a
VERY high load average ~200 and as soon as you issue a disk-io request of any
kind your process hangs. The hang has been happening during a cpio backup of
the system.
This last time we caught some/most of an ooops. I'll include the ksymoops
output and the raw input. I think we may be able to glean more information from
the report, but I'm not really familiar with the ooops output. Let me know if I
can do anything to make the report better.
Here's some info. about the computer.

Compiler: gcc version 2.95.4 20011002 (Debian prerelease)
Drives: software raid1 - 2xMaxtor 4G160J8-ide drives (with the write cache
turned off)
