Are your drives connected to the VIA or the Promise controller? Mine
are both connected to the PDC20265 and running in UDMA-100 mode. There
have been several threads on lkml about corruption on disks connected
to Via chipset IDE controllers, although I didn't follow them in great
detail. Maybe your problem is not related to the host bridge, but to
the IDE controller?

They are connected to Promise, I reserved VIA for CDROM drive.
One HDD runs in UDMA5 mode, another in UDMA2. Corruption is often
when I run md5sum in parallel on both HDDs - in that case almost
no file generates same checksum which was generated using PIO4.
When I run md5sum on only one HDD, there are about 4 checksum errors
in 6GB of data. But I'm more and more inclined to throw this A7V away,
as it is impossible to get datasheet from Promise, and for VIA host
bridge I was just able to slow down normal system operation by factor
of 3... but still with same corruption :-( Just if page could have
4092 and not 4096 bytes ;-)

I have found a way to create the file-system problem!  Just build
the kernel and, from another terminal execute `sync`. The build will
fail with multiple errors caused by corrupted files. The files
are not actually corrupted, though. Just restart the build and it
will complete.

So there is something that `sync` triggers that results in apparent
file system corruption. Once files are re-read, they are fine.
This does not explain the permanent file-system corruption that
sometimes occurs --that may occur during the `umount`.

I don't use IDE. I use BusLogic SCSI, 250 Mb RAM, Pentium-III(2), SMP.
Linux 2.4.1 (no postfix).

FWIW, here's the output of my lspci for A7V with working 1003 BIOS

The patch doesn't work for me. Maybe I need to disable some more of
those North bridge features :-(

Oh bum. Back to testing with "normal" ...
