Re: [E1000-devel] 2.6.36-rc7-git2 - panic/GPF: e1000e/vlans?

Ok, here're the steps to reproduce the problem:

ip link set up dev eth0
vconfig add eth0 10
ip link set up dev eth0.10
brctl addbr brtest
# to bylo ok, sundà to aÅ:
brctl add brtest eth0.10

last command causes panic in few seconds..

Interesting thing is that it're reproducible only for eth0, not for
eth1 (both are onboard 80003ES2LAN)

here's the lspci for those:
06:00.0 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) (rev 01)

last but not least, I've done bisect and it leads to:
commit ae878ae280bea286ff2b1e1cb6e609dd8cb4501d
Author: Maciej Åenczykowski <maze@xxxxxxxxxx>
Date:   Sun Oct 3 14:49:00 2010 -0700                                                                                                                                                                                                      net: Fix IPv6 PMTU disc. w/ asymmetric routes

doesn't seem to me to be related at all, but reverting really seems to fix the problem for me..
I hope it helps..
with best regards
nik
