Hi,

We've able recreate the problem on another platform; this time a
DELL PowerEdge 1650. See
http://www.dell.com/us/en/esg/topics/esg_pedge_rackmain_servers_1_pedge_1650.htm
The configuration is pretty much identical (Single Pentium III 1133MHz CPU,
dual mirrored SCSI drives, Redhat 7.3 running kernel 2.4.18). Please let me
know if you need additional information. Thank you.
