It looks like I would need to see whether I could enhance the
libscg adptation layer for freeBSD/CAM.
But in this case you correctly receive a CHECK CONDITION.
In order to check whether this layer has more problems I would need
to add debug code that s currently missing.
Please note that the probability that the problem is inside your kernel
is much higher than a problem in libscg. This is because the SCSI status
byte is directly copied from the FreeBSD Kernel.
Did you try to send a bug report to the FreeBSD kernel team?
