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
