Description of problem:
I have two systems, one brand new dual Athlon and one ancient 150 MHz Pentium,
on which I've installed RH 8.0 on a SCSI disk replacing RH 7.3.  Both systems
had file systems on a pair of IDE disks formatted as RAID-0.

After the RH 8.0 installations and re-creation of /etc/raidtab, both systems
RAID arrays startet throwing very similar errors of the form:

hdc: read_intr: status=0x59 { DriveReady SeekComplete DataRequest Error }
hdc: read_intr: error=0x10 { SectorIdNotFound }, LBAsec=200, sector=154

as well as

EXT3-fs error (device md(9,0)): ext3_get_inode_loc: unable to read inode block

and similarly scary messages.  Now, I at first thought the problem was due to an
IDE disk failure on the dual Athlon system, and indeed a diagnostic showed
problems with one of the two IDE disks.  However, just now the P150 which was
updated two days ago started throwing similar errors.  It seems highly unlikely
that both systems had IDE disks which failed in the same way right after an RH
8.0 update.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.  Create a two-disk data RAID0 under RedHat 7.3.
2.  Install RH 8.0 on that system.

Actual Results:  Errors and data corruption.

Expected Results:  The contents of the old data disk should have worked fine
under RH 8.0.
