kernels > 2.6.19.7 freezes over epia mii-6000 (VT8633) with sata VT6421 pci controller

[liga <alessioligabue@gmail.com>]

I have a problem with my VT6421 sata controller, after some hours it
freeze bad with all the kernel > 2.6.19.7.
I have tried ~ 10 kernel with the same result (2 compiled by Debian),
it seem to be a bug in sata_via module (but I'm not sure) because I
have tried with a old ide disk the kernels and they runs correctly.
No messages on the kernel serial console.
I hope that you can help me.
Thank you.
Alessio
