Hello,
I've built a new machine with VT6421 add-on card that has two SATA and one
PATA port:
sata_via :00:0a.0: version 2.2
sata_via :00:0a.0: routed to hard irq line 12
scsi0 : sata_via
scsi1 : sata_via
scsi2 : sata_via
ata1: SATA max UDMA/133 cmd 0x00016300 ctl 0x0001630a bmdma 0x000167

Does it settle at UDMA33 or keep going down lower ?

It does not go below UDMA
Hello,
I think that I've found and fixed the problem. There is a copy/paste bug in
vt6421_set_dma_mode() function which causes wrong values to be written to
PATA_UDMA_TIMING register.
This patch fixes a copy/paste bug that breaks DMA modes on VT6421 PATA port.
