Subject: kernel panic on interface flap
Hello,
i was recommended by a nice #kernelnewbies user to post here so please
excuse me if i miss something.
We have a debian squeeze up-to-date box running kernel 3.8.13, intel
e1000e and tg3 broadcom interfaces, dual stack, quagga and few gre
tunnels on a interface.
lspci | grep ther
02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5722
Gigabit Ethernet PCI Express
03:01.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5703
Gigabit Ethernet (rev 10)
04:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet
Controller (rev 06)
04:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet
Controller (rev 06)
If we flap the interface (with gre tunnels and mtu 1524) the kernel will
panic..
