[1.] One line summary of the problem:
random kswapd crashes
[2.] Full description of the problem/report:
kswapd crashes at random times without needing to do anything at all. Only
rebooting the machine "fixes" it as I find no other mechanism for
"resarting" kswapd after a crash. The kernel doesn't go into a panic, it
simply hangs the machine a short while later.
[3.] Keywords (i.e., modules, networking, kernel):
kernel - kswapd
[4.] Kernel version (from /proc/version):
Linux version 2.4.19.vwe.net (root@udder.vwe.net) (gcc version 2.96
20000731 (Red Hat Linux 7.3 2.96-112)) #4 Sun Nov 3 16:26:15 UTC 2002
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)

Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?

[6.] A small shell script or example program which triggers the
problem (if possible)
sorry there's none available as I don't know how to reproduce the problem
and there seems to be no pattern to when it happens.
