VIA VT6421 SATA card still seems to crash many systems

[arnuschky]

I am using a VIA VT6421 SATA card on a 64bit Ubuntu/Natty

Upon accessing a DVD drive connected to the card, the whole server crashes almost immediately. Here the messages I get from the kernel upon the crash:

The log stops there. There seem to be others with this problem:

#724421 seems to be a duplicate of this bug (or the other way round...)

Please note that in my case the issue is not linked to Western Digital hard drives - but I also seem to be the only one attaching a DVD drive to this card. Additionally, the crash is always reproducible. It seems to have nothing to do with high transfer speeds as reported by other people.

This bug is still showing on raring. I read that it was fixed in the 2.6.x branch, but I keep getting the same errors on raring (default iso kernel).
