kernel panic hm ??

[Carlos Carvalho]

Trying this list first, if it's not raid-related I'll go to linux-kernel...

Our raid5 server locked again, with the message "kernel panic hm ??"
displayed 3 times on the console. This is the second time.
Interestingly, it locked roughly at the same time: 6:24 and 6:30. This
suggests some cron process might be triggering it.

I'd like to know if the panic message has anything to do with raid.
Also, the kernel was compiled with egcs-2.91.60 19981201. Should I try
gcc 2.7.2.3?
