Subject: 2.6.35 -> 2.6.36 panic when vlan and promisc with tg3
Date: Mon, 29 Nov 2010 20:17:16 +0100 [thread overview]
Message-ID: <20101129201716.1d0257c4@xenia.leun.net> (raw)
Hi,
only kernel message I was able to capture on serial were:
UG: unable to handle kernel paging request at 01cc921c
IP: [<c034bfce>] vlan_hwaccel_do_receive+0x59/0xd0
*pdpt = 0000000036a2a001 *pde = 0000000000000000
Oops: 0002 [#1] SMP
last sysfs
Then machine dead.
In 2.6.35.x this did not happen (but vlans broken - cannot see vlan
tags with tcpdump),
To reproduce:
ip link set eth0 up
vconfig add eth0 2
ip link set eth0 promisc on
Machines with these ethernet cards I've seen to be affected:
Ethernet controller: Broadcom Corporation NetXtreme BCM5714 Gigabit
Ethernet (rev a3)
Ethernet controller: Broadcom Corporation NetXtreme BCM5752M Gigabit
Ethernet PCI Express (rev 02)
Machine with this card is NOT affected (no vlan hw accel?):
Ethernet controller: Broadcom Corporation NetLink BCM5906M Fast
Ethernet PCI Express (rev 02)

MfG,
Michael Leun
