Hello,
Starting a vm (FreeBSD 13.2) with passthru NIC results a constant flood of
error messages on the host (FreeBSD 14-CURRENT).
The NIC refuses to work in the vm (it works on the host if I turn off the
passthru).
This problem is persistent since 13.1-Release.
(Sidenote: the passthru mostly works under the EOL 13.0-p13 with the same
config, only occasionally showing the symptoms after multiple vm reboots,
and a host reboot solves the problem unlike in 13.1-release 13.2-release
and now 14.0-current)
Ruling out NIC/board hardware fault and specific NIC driver problems, I've
tried with the following NICs:
- Intel I350-t4
- Intel 82580
- Broadcom BCM5720
...in different desktop and server boards (with the latest BIOS):
- Asus M5A99X EVO R2.0
- Asus M4A87TD EVO
- Asus KGPE-D16
