Hi y'all,

coming the 'natural' way through the iwm driver (autoconfig code,
ioctls, fdopen(), I am digressing a bit at the moment and hacking at the
disklabel code. I shall need it soon...

I have re-enabled setdisklabel() and writedisklabel() in
mac68k/disksubr.c, fixed what I think is a minor bug in readdisklabel(),
dropped in some comments and am now able to read and write native
disklabels just fine.

But when I insert a cartridge with a native label and try to newfs(8)
it, the kernel keeps telling me that the device is not configured
(ENXIO, I suppose). I have configured a kernel with SCSIDEBUG and
increased the debug level in scsi/scsi_debug.h to level 4; but the debug
output shows me no trace of a problem. The kernel loads the disklabel
and then appears to just give up silently. 

The end of the trace looks like

Does that ring a bell for anyone?
