I've got another problematic combination: a Maxtor drive with a VP2
chipset. The only way I've been able to get any recent vintage 2.1
series kernel to operate reliably is to disable DMA, either using the
``default DMA'' kernel option, or by running ``hdparm -d0 /dev/hda''
shortly after boot. With DMA enabled, the machine will freeze solid
without a trace at the first occurence of significant disk activity.
With DMA disabled, the same system runs fine for weeks on end.
I've also been unable to get the frame buffer console code working,
resulting in a serious case of penguin envy. I suspect that this just
means that my S3V card isn't up to the task, but if anyone has gotten
this card to work, I'd appreciate some help getting this set up.
