lockup/crash in 2.4.3 (kernel BUG at exit.c:458!)

[Patrick McLean]

After I installed 2.4.3, my system would seemingly randomly hadn, about once a 
day. It hung at least 3 times, but it looks like theres only entries in my 
syslog for 2 of those times, my system is an AMD Thununderbird 1Ghz, 256MB RAM,
VIA KX133A chipset (Abit KT7A), if there's any other info you need let me know,
and please CC me any responses, I'm not subscribed to the list.

I'm not exactly up on kernel internals, and I can't really provide any info about
what could have caused it.

Here's what showed up in my syslog:
