I'm not sure if this is the right place to ask, so please redirect me if
necessary.

An associate of mine (cc'd) is hitting panics in the NVME driver when using
FreeBSD 10.2-RELEASE.  He's using the NVME driver for ZFS cache (L2ARC) and
log (ZIL/SLOG) devices, and he wasn't seeing any problems with it on 10.1.
He filed a bug but I was wondering if there's anything more we can do to
bring this to the attention of someone who might be able to help with it.

The bug is https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203746, and
the panic is in nvme_bio_child_done().

Thanks,
--matt
