I think that the vlan creation/removal code is racy even under /current.
There was some discussion recently about it.

I have unfortunately not heard the discussion. Is it planned to solve the 
problem in the near future?

I re-introduced the change that I previously rolled back to get things
working, and then upgraded pfil.c to 1.34 and built a new kernel.  This
worked fine -- you've obviously corrected the problem.  :)

About the NFS hang:

Noted - but I haven't been able to get into DDB.  I though Ctrl-Alt-Esc
in the first console (the Ctrl-Alt-F1 one) should do it, but it doesn't.

Not much.  Server:

nfs_server=YES and nfsd_flags="-n 16" in rc.conf.

Client:

nfs_client=YES in rc.conf, and "rw,bg,intr" as mount options.

Hm. Maybe I should change to a TCP mount, and see what happens...

Re: Recent amd64 auich panics

[Chavdar Ivanov]

Indeed the kernel from overnight boots OK and sound works. There is some
problem with the sound in this configuration though - I use from time to
time audio/moc on this machine and noticed it has become decidedly choppy -
I don't know when, as it is the same with earlier working kernels (but
perhaps two months ago it was OK). Of course the reason for this may lay
outside NetBSD - VirtualBox sound emulation driver, Windows 10 driver etc.

I asked to try a patch protecting vlan creation and removal with a mutex.
