2.3.23-pre5 oopses everytime it starts swapping. /proc/meminfo shows the
following:
total: used: free: shared: buffers: cached:

I have only got 32 MB of swap so this is clearly wrong. The oopses are as
follows:
ksymoops 0.7c on i586 2.3.23. Options used
-v /usr/src/linux/vmlinux (specified)
-k /proc/ksyms (default)
