>Synopsis: Panic on boot with Hyper-V since Jun 17 snapshot
>Category: kernel
>Environment:
System : OpenBSD 6.7
Details : OpenBSD 6.7-current (GENERIC.MP) #375: Sun Jul 26
11:26:37 MDT 2020
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
Booting -current on Hyper-V with hvn(4) results in a panic after
"starting network".
This seems to only affect the multi-user boot; hvn(4) still
works flawlessly on the ramdisk.
Last working snapshot:
OpenBSD 6.7-current (GENERIC.MP) #273: Mon Jun 15 19:13:12 MDT 2020
First non-working snapshot:
OpenBSD 6.7-current (GENERIC.MP) #278: Wed Jun 17 12:18:35 MDT 2020
Below is the serial output including ddb trace and ps.
>How-To-Repeat:
Boot OpenBSD-current on Hyper-V with a hvn(4) network adapter.
>Fix:
Unknown. As a workaround, disabling hvn(4) via "boot -c" does
not result in a panic.
