HD is a DGVS and not a DRVS, sorry.

Now I tried again with 2.2.2 and 5.1.12 and without LUN (already had it in
2.2.1)  I still get an kernel panic.

I'm wondering why there is a difference between downloading sequencer code

2.0.34> (scsi0) Downloading sequencer code... 413 instructions downloaded

Any ideas,
