freebsd stable - Apr 2019 - Rare NVME related freeze at boot (was: Re: NVME aborting outstanding i/o)

Hi all,

in addition to the aborted commands every dozen of system boots or so
(this order of magnitude) the kernel simply hangs during initialisation of
one of the NVME devices:

https://cloud.hausen.com/s/TxPTDFJwMe6sJr2

The particular device affected is not constant.

A power cycle fixes it, the system has not shown hangs/freezes during
multiuser operation, yet.


Any ideas?
Patrick

What normally comes after the nvme6 line in boot? Often times it's the next
thing after the last message that's the issue, not the last thing.
