Package: linux-image-4.9.0-3-amd64

Version: 4.9.30-2+deb9u2

When starting an ancient Windows Server 2003 virtual machine on a fully
updated stretch host, the host will crash repeatably about 10 seconds
after start. Kernel logging was implemented over netconsole, so I could
capture the kernel output stating

kernel BUG at /build/linux-9uDFZV/linux-4.9.30/drivers/nvme/host/pci.c:495!

Hardware is dual E5-2620v4 on Supermicro 10DRI-T with two SAMSUNG
MZQLW960HMJP-00003 NVME disks (mdadm RAID-1).

drivers/nvme/host/pci.c wasn't changed up to 4.11.8, the crashing
function nvme_setup_prps still the same in 4.12rc7, so I guess the bug
is still there.
