Hi,

on an HP LH 3000 Netserver with the onboard Netraid Controller Redhat 
Linux 6.2 crashes under heavy load. The console displays the following 
Text:

scsi: aborting command due to timeout: ...

I4ve installed the Bugfix Package ( New Kernel ) from Redhat - Date 2000-
06-20 with the new Megaraid Driver included from AMI Ver.1.08b ...

This doesn4t fixed the Problem. HP says, the Hardware is Ok. We made 
various Checks ...

My System:

HP LH 3000 Netserver
Dual PIII - 733 Mhz
512 MB Ram
4 x 36 GB Harddisks
Main Bios Version 4.028
Netraid Bios Version E.01.01

A little bit out of /var/log/messages :)
