NVME-related crash on 15.0-BETA1

[fmc000]

I was debugging some suspend/resume problems I happen to have on my system and decided to give kern.vt.suspendswitch=1 a try, so that I could see my console in case of problems...and boy I was right!

Of course a forced poweroff a a subsequent poweron show no errors.

I guess a PR is in order unless someone has ideas?

"The Version should be 15.0-RELEASE but it's not available in the dropdown list."
I also ran into this. I think because they want to reserve "15.0-RELEASE" for the official release, I'm not sure though. There's also the subtle distinction between the branch label releng/15 versus official minor releases that are not on a pre-release cycle.

Yeah, my thoughts too. Anyways, I tracked down the issue to the second suspend/resume cycle, which fails all the time whilst the first suspend/resume cycle seems to work reliably. Definitely a regression when compared to 14.3 .
