That's good to know.  I am beginning to suspect that I have a bad
controller.

I have not used the GENERICAHBBT kernel.  I am rolling my own kernel
with the following config.  If there is a way that you can make your
kernel ftp'able, I would love to try it.  That would help me confirm
my problems.

What version of the boot blocks are you running?  I am using the 1.8
blocks due to recent problems with the latest ones.  I have also tried
the board at irq 12 and 11.

Right after I see the drive information for the first target, there is
a long delay, then the message "cmd fail" is printed to screen.  That
information is followed by the following printf from sd.c.

	if (sd_scsi_cmd(unit, (struct scsi_generic *)&scsi_cmd,
	    sizeof(scsi_cmd), (u_char *)&scsi_sense, sizeof(scsi_sense),
	    2000, flags) != 0) {
		printf("could not mode sense (4) for unit %d\n", unit);
		printf(" using ficticious geometry\n");

Any help is greatly appreciated.  I am also sending this to the list.
