Kernel crash (2.4.27)

Kernel crash (2.4.27)

[Miika Pekkarinen]

We had 2.4.25-grsec kernel which crashed after about 201 days of
uptime. After that we compiled 2.4.27 kernel with grsecurity and that
kernel crashed very soon. Uptime was less than a day.
Unfortunately kernel was not compiled with frame pointers. Now we have
frame pointers enabled and if it crashes yet again we'll post some
more info.

Swap partition was tested with bonie++ and badblocks. No errors were
found.  The partition is also on a raid-5 device.
