Hmm......I suppose that's possible. Typically when I've seen these
particular errors, the drive was on its way out. Those log messages are
typical of a drive that has developed "bad" sectors and bad sectors are
problem that never gets better on its own. I would still be tempted to
back the data up and run some kind of thorough surface scan.

What if you have more than one CPU? AIUI, disabling APIC support is not
really an option on an SMP system like my dual PII-450 machine.

Hmm.... Try this 'dd if=/dev/hda of=/dev/null' and see if you get any
messages in the logs.

Oh I don't use them either except for my EPIA tinkering. I've learned
some hard (read as expensive and time-consuming) lessons about using
non-Intel chipsets. I look at it like buying cheap tools, I simply
can't afford them.
