[CentOS] sata_via freeze

Hi all,

I have a machine with a Assus P5VD2-MX, it has a VIA chipset.  The
problem is sometimes without any reason all freeze, can't use network
and when I type a command in shell occur a I/O error.
I already test memory, and the problem are in two similars machines.

I see in CentOS foruns someone with the same problem using the
sata_via driver but without an answer.

I'm running Centos 5, in BIOS disable Jmicron raid, and the sata is in IDE mode.

Thanks all.
