--- Comment #61 from Len White <lwhite at nrw.ca> ---
I've recently hit the error nvme0: Missing interrupt on 10.3 and 12.0-current. 
I discovered a workaround that may help lead to a proper fix, though I don't
know for certain if the Missing interrupt is related to resetting controller
message.

If I have nvme_load="YES" and nvd_load="YES" in /boot/loader.conf, I get
missing interrupt every time, the more the device gets used the more of the
messages show up.  Each time that message is shown it seems the read/write
operation fails as the end result is corruption (AND oddly half the time my
intel ix card doesn't work properly when this happens it will spit out ix0:
TX(0) desc avail = 34, pidx = 87, link status stays no carrier)

If I load nvme/nvd AFTER the system finishes booting, it behaves normally and
doesn't affect ix.

So it seems loading nvme/nvd early in the boot process causes some kind of
interrupt conflict with other driver(s).
