 I've tried r357763 and it panics exactly same way. My system doesn't have
ZFS too (it is NanoBSD image for small router).

 I didn't update this "firmware" for almost a year, and don't have results
for revision between r349299 (works) and r357763 (panics). It is too much
for bi-sect :-(

 I'll try r357508, which works for me on other host, but I suspect it is
HW-related and not universal. But, again, r349299 works rock-solid.
