| |
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
