Thanks for letting us know!

Could you provide more details about the exact setup and the sequence of 
commands that lead to the crash? If you can narrow it down to the actual 
command that caused the crash that would be very helpful.

Also - are you testing from Linus or net-next tree? If you are not using 
net-next, could you give it a try and see if you can reproduce it there?

Could you provide the output of lspci -vvv and a kernel config?

Thanks,

Hello Emil,
sure, I'll gladly provide all the required data. I'll prepare it during Wednesday,
sorry I can't do it sooner.
in the meantime, Rafael created bugzilla entry, here's the link for the reference:

https://bugzilla.kernel.org/show_bug.cgi?id=20462

have a nice day

Hello Emil,

I tried it now, I can still 100% reproduce with 2.6.36-rc7-git2, but
with 2.6.36-rc8-git5 it works OK. So it certainly got fixed in the meantime!
I'll therefore close the bug in BZ.

have a nice day!

best regards

nik

[Nikola Ciprich]

so unfortunately I have to take back what I just wrote :(
the problem still persists, it just seems to be more random
so I'll try to separate the exact command that causes the panic..

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

[Nikola Ciprich]

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, sundá to až:
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)
	Subsystem: Super Micro Computer Inc Unknown device 0000
	Flags: bus master, fast devsel, latency 0, IRQ 65
	Memory at d8300000 (32-bit, non-prefetchable) [size=128K]
	I/O ports at 3000 [size=32]
	Capabilities: [c8] Power Management version 2
	Capabilities: [d0] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable+
	Capabilities: [e0] Express Endpoint IRQ 0
	Capabilities: [100] Advanced Error Reporting
	Capabilities: [140] Device Serial Number 5a-19-34-ff-ff-48-30-00

06:00.1 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) (rev 01)
	Subsystem: Super Micro Computer Inc Unknown device 0000
	Flags: bus master, fast devsel, latency 0, IRQ 66
	Memory at d8320000 (32-bit, non-prefetchable) [size=128K]
	I/O ports at 3020 [size=32]
	Capabilities: [c8] Power Management version 2
	Capabilities: [d0] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable+
	Capabilities: [e0] Express Endpoint IRQ 0
	Capabilities: [100] Advanced Error Reporting
	Capabilities: [140] Device Serial Number 5a-19-34-ff-ff-48-30-00

last but not least, I've done bisect and it leads to:
commit ae878ae280bea286ff2b1e1cb6e609dd8cb4501d
Author: Maciej Żenczykowski <maze@google.com>
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

Hello!

I seem to have same problem but with r8169 device:

When I tried to boot, computer freezes at vlan_hwaccel_do_receive  
(gpf), with computer completely frozen and not responding to sysrq.  
With quick search I found this thread and figured problem must be in  
shared hardware vlan acceleration code. So I disabled vlan hwaccel in  
r8169 driver (CONFIG_R8169_VLAN=n) and got computer booting ok.

Network is set up with two VLANs and two bridges:
  bridge name	bridge id		STP enabled	interfaces
  br0		8000.xxxxxxxxxxxx	no		dummy0
							dummy2
							dummy4
							dummy6
							eth0.0000
  wanbr0		8000.yyyyyyyyyyyy	no		dummy1
							dummy3
							eth0.0009

Is there any more info, like a stack trace?  We just saw this on
one of our more complex setups.  Kernel is 2.6.36, with some patches,
including a proprietary module:

I re-compiled this kernel with symbols, and the crash points here.  We'll
try to reproduce with this newly compiled kernel, in case that merely compiling
with symbols changes the offsets.
