I actually was running loadbsd version 2.4. The OS is Kickstart
version 37.175 and Workbench is 37.67.

I then used the old loadbsd2.0 and I got a little farther.

Now I commented out all the scsi drivers in my GENERIC file, except
ahsc0, also I suped the very latest 16.05.1994 stuff and did make
depend;  make again, now The kernel had a problem with sd.c (the
one in /usr/src/sys/scsi, not the one in /usr/src/sys/arch/amiga/dev)
loadbsd resulted in an undefined function
I found it in the /usr/src/sys/arch/amiga/gtsc.c file, so I just
copied it into the sd.c file and the compile worked.
The function only contains:

But when starting the sysem with the new kernel I got the following:

ahsc0 targ5 lun0 <Quantum LP105S 9101094053.1> SCSI2 direct fixed
sd5 at scsibus1: 100MB, 1211 cyl, 4 head, 42 sec, 512 bytes/sec
ahsc0 targ6 lun0 <Quantum LP240S GM240S01X6.4> SCSI2 direct fixed
sd5 at scsibus1: 234MB, 1818 cyl, 4 head, 65 sec, 512 bytes/sec
zthreebus0 at mainbus0

here the machine hangs with the HD light on steady. When I press a key
I get a panic with the PC at 0001A34E.

Is this related to the dk_establish function?
And why SCSI2? I thought A3000 are SCSI1. Just in case it matters my
SCSI chip is the A version rev 00-08.

Any Ideas?
