Because of the brain damadget architecture from this controller (Bus A has an external and an internal connector, bus B has only an internal connector) I've changed the Bus numbering in the EISA Setup, so that channel B is the primary bus and channel A the secondary. This configuration is running fine, but the now primary channel B is detected as bus #1 and the secondary channel A as bus #0. This makes no problems so far. But when I connect an external SCSI disk later whitout hardwiring the devices in the kernel the kernel is booting fine (using da0 in the bootloader) but when it try's to mount the root disk it panics, because there is no / filesystem on the now new disk from the second channel A that is now da0! Could we please change this bus numbering behavior so that the in the EISA Setup defined "primary" SCSI bus get's the bus #0 even when it is channel B ?
