You might want to checkout your kernel archive under /people/hedrick at
patch it with the latest ide patch from there.
Also in that directory are some txt files displaying warning specific to a
couple of ide controllers.

> I originally suspected that this was a problem with the hard discs as the
> BIOS has never detected FUJITSU MPC3102AT hard discs correctly (the BIOS
> recognises them as 648Mb hard discs, where they are actually 9765Mb). But
> our recent experiences with two brand new (i.e. totally unused) MPC3102AT
> hard discs suggested that the fault may lie elsewhere.
>
> We installed the MPC3102AT into a computer, partitioned and formatted the
> disk. Running e2fsck on the disk displayed many disk errors and send
several
> inodes to lost and found. The same errors occurred on the second MPC3102AT
> hard disc. We placed the hard discs into another computer (a PII 333),
where
> the BIOS correctly recognised them this time, and exactly the same problem
> occurred. The kernel used in both cases was 2.2.12.
>
> The IRQ/DMA timeouts are problematic as they are seem to be related to
> some major disk corruption. The kernel doesn't report the disk errors
> until too late, and we end up losing a about 90Mb of data to lost+found.
