Ok. So what I'm exactly looking for:

Cases of harddrive corruption (that is, trashing your fs,
reading/writing bad data) on VIA chipsets. UDMA-caused CRC errors don't
fall into this category, they're harmless to the data.

Preferably with the driver from the 2.4.0 kernel. If possible, try also
the VIA 3.11 driver posted to the list earlier. If you don't have it, I
can e-mail it to you.

Don't use any hdparm command in your init scripts (this is important)
with the VIA driver and 2.4.0, setting the speed or dma usage with
hdparm would interfere with the driver autotuning.

If you fear to test, you can mount your fs readonly (no corruption can
happen) and use your swap partition for read-write test. You can even
mke2fs the swap for a while.

Anyone who experienced this kind of problems with 2.4 and the VIA
driver, please speak up, so I can fix it.

I'm not currently looking for success reports, I've already got success
reports for every type VIA IDE chip out there.

I'll need the motherboard type and revision, lspci -vvxxx, dmesg,
hdparm -i and /proc/ide/via listings ...
