Debugging I/O errors?

[Roy Sigurd Karlsbakk]

Hi all

Stresstesting a SATA drive+controller, I get the error below after a  
while. How can I find if this error is due to a controller failure, a  
bad driver, or a drive failure?

thanks for all help

Running an unpatched 2.6.18.1

This is a SIS controller:
01:03.0 RAID bus controller: Silicon Image, Inc. SiI 3114 [SATALink/ 
SATARaid] Serial ATA Controller (rev 02)
        Subsystem: Silicon Image, Inc. SiI 3114 SATARaid Controller
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop-  
ParErr- Stepping- SERR+ FastB2B-
        Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium  
>TAbort- <TAbort- <MAbort- >SERR- <PERR-
        Latency: 32, Cache Line Size: 32 bytes
        Interrupt: pin A routed to IRQ 10
        Region 0: I/O ports at dc00 [size=8]
        Region 1: I/O ports at d480 [size=4]
        Region 2: I/O ports at d400 [size=8]
        Region 3: I/O ports at d080 [size=4]
        Region 4: I/O ports at d000 [size=16]
        Region 5: Memory at ff8efc00 (32-bit, non-prefetchable)  
[size=1K]
        Expansion ROM at c6a00000 [disabled] [size=512K]
        Capabilities: [60] Power Management version 2
                Flags: PMEClk- DSI+ D1+ D2+ AuxCurrent=0mA PME 
(D0-,D1-,D2-,D3hot-,D3cold-)
                Status: D0 PME-Enable- DSel=0 DScale=2 PME-

The drive is a seagate 400gig thing (dunno how I can find what),  
libata is alone at IRQ10.
