Hmm, the new code should be printing out the asc/ascq description if the
asc and ascq are non-zero. As far as that goes, it's the same as the old
code. Try the attached patch and see if you get any additional printouts.

Well, I'm curious to see why you're only getting back unit attention
instead of the full sense information. That seems kinda odd.
You might also try powering the device off and back on again and then see
what camcontrol reports via 'camcontrol tur pt0 -v'. (It should be the
same as the kernel, since the code is the same.)
