::sata_sil & sata_via make silent coruptions on FS

Hi!

sata_sil & sata_via make corupptions on opensuse 12.2, 12.3 and Knoppix 7.0.5
in the X86_64 variant. Testing with knoppix in the i386 variant show no problems.

For both drivers and cards are the same problem:

Kernel use automaticly the right modul, activate them and mount the HD.
But by FS-operations (R/W, copy files..) all seems right else the HD are very slow. No errors, no suspects appears. Only when checked the files shasum we see that most files are corrupted. (EXT4)

The drive speed are ~6MB/s when wrong and ~35MB/s when use on i386 (knoppix)


Cards are PCI2STATA, eg:

> lspci:

RAID bus controller: Silicon Image, Inc. SiI 3112 [SATALink/SATARaid]
Serial ATA Controller (rev 02)
...
Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 19
...
Memory at febffc00 (32-bit, non-prefetchable) [size=512]
Expansion ROM at feb00000 [disabled] [size=512K]
Capabilities: [60] Power Management version 2
Kernel driver in use: sata_sil

The card has an own interrupt:

> cat /proc/interrupts
...
 19:         16      35480   IO-APIC-fasteoi   sata_sil
...


Please help me to use the drivers, and sorry for bad english.

What can i do to help you to fix this bug?
