2.6.0-test2: SATA errors, not usable

2.6.0-test2: SATA errors, not usable

[Ricardo Galli]

I'm testing SATA with 2.6.0-test2 with a Intel P4 i875P chipset. The disk is 
recognised correcly, but right after trying any kind of access (hdparm, 
fdisk...) it starts to give the following errors:

...
ICH5-SATA: IDE controller at PCI slot 0000:00:1f.2
ICH5-SATA: chipset revision 2
ICH5-SATA: 100% native mode on irq 18
    ide2: BM-DMA at 0xef90-0xef97, BIOS settings: hde:DMA, hdf:pio
    ide3: BM-DMA at 0xef98-0xef9f, BIOS settings: hdg:pio, hdh:pio
hde: ST380013AS, ATA DISK drive
...
hde: max request size: 1024KiB
hde: host protected area => 1

 hde: hde1
...
hde: dma_intr: status=0x51 { DriveReady SeekComplete Error }
hde: dma_intr: error=0x40 { UncorrectableError }, LBAsect=70, high=0, low=70, 
sector=0
end_request: I/O error, dev hde, sector 0
Buffer I/O error on device hde, logical block 0
Buffer I/O error on device hde, logical block 1
Buffer I/O error on device hde, logical block 2
...


I tried it with 2.4.21 and 2.4.22-pre9 with the same results. 
Also changed the BIOS to put in "compatible mode" (as opposite to sata native) 
and got the same errors.

In all cases, the disk is unusable (a seagate barracuda 80GB).

Regards,
