viaide panic

[John Klos <john%ziaspace.com@localhost>]

Hi,

In trying to get a SATA controller working with NetBSD 4 on macppc, I 
bought a VIA VT6421A combo SATA / PATA controller because I saw that it 
was specifically supported by viaide (my Silicon Image SiL 3512 
controller gives me device timeouts unless it's doing PIO).

 With the card installed, the system boots, but with a SATA drive attached 
to the card, it panics:

acardide0 at pci0 dev 13 function 0
acardide0: Acard ATP860-A Ultra66 IDE Controller (rev. 0x01)
acardide0: bus-master DMA support present
acardide0: primary channel wired to native-PCI mode
acardide0: using irq 23 for native-PCI interrupt
atabus0 at acardide0 channel 0
acardide0: secondary channel wired to native-PCI mode
atabus1 at acardide0 channel 1
viaide0 at pci0 dev 14 function 0
viaide0: VIA Technologies VT6421 Serial RAID Controller (rev. 0x50)
