I got the following oops on 2.4.25-pre7 using a Maxtor SATA drive on a
SiI3112 controller (siimage driver). The drive has bad sectors, hence
the DMA timeout. It doesnt oops every time the sector is read however.
Can just give:
hde: status timeout: status=0xd8 { Busy }
ide2: reset phy, status=0x00000113, siimage_reset
hde: drive not ready for command
ide2: reset: success
hde: sata_error = 0x00400000, watchdog = 1,
siimage_mmio_ide_dma_test_irq
hde: dma_intr: status=0xd0 { Busy }
ide2: reset phy, status=0x00000113, siimage_reset
Kernel config is attached (fairly standard SMP).
I havent worked out exactly what causes the oops, but with a SATA drive
there is really no point retrying in PIO anyway...
I havent tested this drive on libata, can do later.
hde: dma_timer_expiry: dma status == 0x21
