hi,

i cvsuped after a long time (3 months), kernel panics when boot,
in ata_pci_dmareset()

my pc has
atapci0: <SiS 961 UDMA100 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xff00-0xff0f at device 2.5 on pci0

svn r183723 works, but r183724(and later) cause panic


any suggestions?


regards,

Showing us at least some part of the panic, if not a full backtrace,  
probably would be helpful.

Try disabling DMA at the loader with
set hw.ata.ata_dma="0"
