are you sure this is a DMA problem. there are lots of places in the kernel that return Ebadctl.

DMA helps a lot on venti formatting. | However, I saw this ominous message on my console when | installing another tip9ug host on VMware ESX 3.0 Server | which only supports Buslogic SCSI adaptor. | | init: starting /bin/rc | echo: write error: bad process or channel control request | echo: write error: bad process or channel control request | | I guess someone tried to turn DMA on for the SCSI drive and failed.
