A known issue. Some weeks ago discussed on the CentOS list:
http://lists.centos.org/pipermail/centos/2005-May/005824.html
Don't know why the bugzilla ticket is restricted
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=121434
Very interesting reading - thanks for the link. Some of those posts
suggest that the newer 3Ware firmware may "improve" the issue.
Otherwise, I guess I'm in the market for a different 4 channel RAID 5
SATA card. Any recommendations?
