Is there anything that can be done about these? Running 2.4.19 on a
piii-800, 512MB, scsi hardware raid.
Seeing tons of these messages (flooding syslogs) whenever I do much I/O
to the drives.
Is there any vm tuning that can be done?

These are "fixed" in 2.4.20-pre so you should try that, if for nothing
else than testing that it works well. The old setup is just fragile.
