Problems in 2.4.0-test12

[Arthur Pedyczak]

Hi all,
I had been running 2.4.0-test12 for 7 days. Worked great. Then the
system just froze. No oopses,
no log entries, no telneting to the box, no SysRq. Hard reboot. Some 12
hrs. later I got the following Oops in xfs. At that time I was
installing Corel Photopaint and the install was going through fonts. The
oops is _NOT_ reproducible (after reboot installation went fine).

ksymoops 2.3.4 on i686 2.4.0-test12.  Options used
     -v /usr/src/linux/vmlinux (specified)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-test12/ (default)
     -m /usr/src/linux/System.map (specified)
