--- Comment #1 from Martin Birgmeier <d8zNeCFG at aon.at> ---
I just tried this again with head as of r343663, again with an immediate panic
when accessing the virtual network interface.
I can run FreeBSD under Hyper-V only using the legacy network adapter. Alas,
this is de(4) which is slated for removal soon. So the problem is becoming more
pressing.
Is there anyone running FreeBSD successfully under Hyper-V on Windows 10 Pro?
If yes, are there any special settings needed?
Here is a kgdb session of the crash dump written from ddb. Note that if_de was
not loaded when the crash occurred, I guess it is only read by kgdb because I
changed /boot/loader.conf back to using it.
