Hello, everyone!

Today I have upgraded my chief's laptop from 5.2.1-R to -CURRENT 
(cvsuped yesterday).

CURRENT kernel won't boot
ATA driver is causing problems (and panics on boot)

atapci0: <SiS 961 UDMA100 controller> port 0x110b-0x1

kernel tells me that it can't use ATA66 DMA mode because of cable
or device not supporting it. then it tries (about 4 times) to switch to DMA33
and finally panics.

Fatal trap 12 while in kernel mode
Panicing process = taskqueue

All Messages are avaible on request (will type manually)

For now I have set hw.ata.ata_dma="0" in /etc/loader.conf
and it works in PIO4 now, but it is slow like hell.

Someone please help me ;))

Cheers,
          AL.
