Forgot to mention, I'm using 2 passthrough PCI-e cards. But the problem is=

Hello, dear friends :)
I"m on 13.0-p3. Suddenly, after some hardware reconfiguration (PCI-e cards =
exchanged slots) my bhyve stopped working.In particular, in my Win 10 VM, i=
t goes as far as offer to type in BitLocker password, after which starts bo=
oting and immediately crashes. However, I tried to start afresh without ANY=
disks attached, except Win 10 installation ISO. Gets as far as 'type a key=
to boot from CD', then crashes on an attempt to boot.
This is the message that I see on the screen:./bhyve-1: line 11: =C2=A02954=

For the purity of experiment, I tried it with a fresh installation on the s=
ame machine -- same thing. So I assume it is hardware related. As such, I r=
ecall in the past there was a patch=20
NOTE: in the past, pre-13.0, I had similar crash related to a PCI-e card wi=
th multiple bars, as described here:https://forums.freebsd.org/threads/bhyv=
e-pci-passthru-windows-10-problem.74265/
However, the patch cured that, and it has long been incorporated into the b=
hyve code... But the card is still in my machine, it's a 4-port Intel NIC. =
I haven't yet tried removing this or that card from my system... didn't hav=
e the time yet. But I'd like to keep having it, of course...
My question is, how can I debug this crash? In dmesg it only says:pid 2954 =
(bhyve), jid 0, uid 0: exited on signal 6=20
