SCSI Bus Reset on Dell PowerEdge 1600SC using RHEL 3 Linux

Hi,

I am trying to use my Dell PE 1600SC box for running RHEL 3 Linux. I get this weird SCSI Bus Reset messages on my console and the machine freezes for a few seconds.. It all starts working fine again till the next freeze. Does anyone know what the problem is or how I can fix this? Any Help is higly appreciated..
