oops from crashed kupdated and kswapd

[Karel Krecmer <Karel.Krecmer@vsb.cz>]

Hi,
Some daemons (kupdated and others) crashed on my
Debian unstable, kernel 2.4.17 with xfs patch.
I found in syslog some info (see below) about crash.
I would like to this information will be useful.
regards
          Karel
