Kernel crash - reboot or hang

Kernel 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?

A serial console is probably your best bet.  You if your mail spool is on
reiserfs, you probably want to apply the dir fsync patch (included in
2.4.3pre and the latest ac stuff).

kdb with a serial console.
