Hello
After 4 days of uptime the new 2.4.20 kernel with HTB3 (previously we used
HTB2 and 2.4.9-31) oopsed and in short time I could not even ssh to the
system. Here is the ksymoops filtered message:
ksymoops 2.4.8 on i686 2.4.20-xfs. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.20-xfs/ (default)
-m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

After the oops applications that were trying to write to the /var (xfs)
partition were hanging in D state. We will reformat it and reboot with a
vanilla 2.4.20 having the same config except the XFS filesystem.
Help ?
