UDMA2 on OSB4? Weird.
from serverwoks.c:
/* If we are about to put a disk into UDMA mode we screwed up. Our code assumes we never _ever_ do this on an OSB4 */
if(dev->device == PCI_DEVICE_ID_SERVERWORKS_OSB4 && drive->media == ide_disk && speed >= XFER_UDMA_0) BUG();
I need more data: .config (2.6.5/2.6.6) and full dmesg output (2.6.5/2.6.6).
