I haven't gotten any panics on either. I just did a make clean && make buildworld && make buildkernel && make clean (and ran the final make clean 9 times for good measure) on the second machine to try to reproduce the reported panic, but it worked fine. Both machines are running FreeBSD 8.0-STABLE/amd64 with ZFS from -CURRENT as of Dec 4, plus your patch. This patch is essentially mandatory for me to be able to run ZFS, since otherwise I can't backup my ZFS pools... - Pete Curry
