FreeBSD 6.0-CURRENT with GENERIC kernel built 27th Sep.
On a SunBlade 100 I see these messages regularly when
dma is enabled. The messages go away when I either use
atacontrol to set the mode to PIO4 or set hw.ata.ata_dma to 0
I do get data corruption on the disk if left in DMA mode.
dmesg:
GDB: no debug ports present
KDB: debugger backends: ddb
KDB: current backend: ddb
