Public bug reported:
My set up is a Cisco UCS c240 server with an Intel NVMe 1.6TB drive
running VMware ESXi version 6.0U2. NVMe device is made available as a
PCI passthru device and not claimed by ESXi kernel. This NVMe device
when added to a Ubuntu 16.04.2 running kernel version 4.4.0-62 and above
does not boot, kernel does not boot fully and hangs for while before the
VM powers off. However, running kernel versions 4.4.0-43, 4.4.0-53,
4.4.0-57, and 4.4.0-59 everything works as expected. Earlier versions of
the kernel also do not work. Here is a short list of the I tested with
4.4.0-31 -> kernel panic (different issue)
4.4.0-43 -> works
4.4.0-53 -> works
4.4.0-57 -> works
4.4.0-59 -> works
4.4.0-62 -> fail
4.4.0-64 -> fail
4.4.0-75 -> fail
4.4.0-77 -> fail
4.8.0-51 -> fail
