Hi,

Let me know if I should be posting this elsewhere.

I'm running OpenBSD 4.5 i386 on an IBM x336 server, as newer versions
don't work with the Broadcom network interfaces [1]. I installed it
about a week ago, and everything was working great until I got the
following on the console (retyped). I ran a trace as per the FAQ:

[lots of vlan: lines; probably me adding the interfaces a few days ago]
vlan80: initialized with non-standard mtu 1496 (parent trunk0)
vlan85: initialized with non-standard mtu 1496 (parent trunk0)
vlan61: initialized with non-standard mtu 1496 (parent trunk0)
vlan1: initialized with non-standard mtu 1496 (parent trunk0)

dmesg output is below [2]. Is this a known problem that's fixed in 4.7?

Cheers,

Patrick

you realize obsd4.5 isn't supported any longer since 4.7 was released.

regardless you if you are planning on running obsd4.5, you should at
the very lease apply currently published patches under errata4.5:

	http://www.openbsd.org/errata45.html

I wonder whether errata 002 is relavent in your case, but I am not sure.

Fair enough. I've managed to get 4.7 working by reverting
/sys/dev/pci/pci.c to 1.72, as suggested in that thread, so I guess
I'll try that.

Cheers,

Patrick
