Hi,
Okay the problem is solvable, and as I have supposed, I did something
wrong doing the quirk.
I commented out all synchronize chache stuff in scsi_da.c and voila, I
can mount my device. (it just has only /dev/da0)
So I will engineer the correct format of the quirk and post a patch
then.
Regards,
Tino
