>How-To-Repeat:
I have a script which is writing files out to tape from ad1 using tar, ie
foreach file
tar -b 128 -zcvf /dev/nrsa0 file
done
Takes a few hours to trigger it but it's happened 3 times now (though I only
got a panic on the last one as my /var was too small before now)
This kernel has the atapicam option enabled if it matters.
I am rebuilding with debugging to get a better stack trace.
