Nope, nothing with SCSI AFAIK, and that is part of the reason I have not
been able to offer more clues, I do not use IDE much, the IBM Deskstar 40gig
I bought to hold divx files is sitting here on my desk dead. SCSI costs
more, but the headaches of IDE are not worth it. Sanity still makes SCSI
the defacto on servers.

I'll speculate that we're seeing these errors on so many machines about the time SuSE (and other *nixes) started supporting DMA. It could simply be crappy hardware, but nobody noticed as long as DMA wasn't enabled. Sort of like the way MS-DOS will run fine on crap hardware that will crash immediately if you install Linux or Windows on it.
I'm also wondering: has anyone seen these errors on scsi disks, or is it strictly an IDE problem?

Hi Alexandr.
DMA is enabled automatically by the default SuSE kernel in 7.3. The "backup" kernel (vmlinuz.suse) doesn't use DMA so you may try this one instead. It can be selected by LILO and checked by hdparm:
I think I have the option to select vmlinuz.suse at boot_up ?.
# /sbin/hdparm -v /dev/hda
/dev/hda: multcount = 16 (on) I/O support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 2491/255/63, sectors = 40031712, start = 0
Here's mine:
# /sbin/hdparm -v /dev/hda
/dev/hda: multcount = 16 (on) I/O support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 4865/255/63, sectors = 78165360, start = 0
The variable START_IDEDMA="yes" is in /etc/rc.config in SuSE 7.2 but not in 7.3, so may forget about it.
Yes nothing to do there.
IBM provides a utility called Drive Fitness Test (DFT) which checks its disks for HW errors. It's quite good if you want to make sure the disk is really bad. I wonder if there is a similar utility for Seagate disks. (I haven't searched for it.)
Ok. I'll have a look for that tool on the Seagate homepage.
