Hi!
Ok, just for a test, before I finish the 2.2 version of the new VIA IDE
driver, could you try with the 2.4.0 kernel if it fixes the behavior?
By the way, what motherboard is this?
Andre: Thanks for sending this to me, this is the case I was looking for
- true data corruption on 2.2 kernel. Now I hope my new driver fixes
this.
