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 Copyright (c) 1992-2004 The FreeBSD Project.
