>Release:        FreeBSD 2.2-960323-SNAP i386
>Environment:

	Intel P5-133 SuperMicro motherboard with Adaptec 2940 SCSI 
controller.  Has ATI-Mach 64 graphics card and two Connor Disks 
(2 GB and 4GB).  Has a NE2000 ethernet adapter.  Machine serves as 
a news server,  X server  and file server.

>Description:

	This machine hangs up unpredictably upto a few times a day.  
Suspect race conditions with the disk drives but this is just intuition.

	Was wondering if this is a known problem and would like suggestions
as to whether I should try a different SCSI controller (Buslogic) or fall
back to the 2.1 Release which was fairly stable under similar circumstances.
