SubjectKernel crash - reboot or hang

Hello,

I NEED TO TRACE THIS!!!

I had two crashes with 2.4.2 and 2.4.2-pre2 on my local SMTP/POP3/SAMBA/WWW
server (once under some load and the second one - with 2.4.2-pre2 - while
it was almost idle).

The machine is an HP Netserver LHII without the standard raid card that
comes with it (see bellow for dmesg output for a better description of
hardware).

I do not see any corruption nor any messages in logs.


Should I use kdb or just remote logging would do the job?
