Package: linux-image-2.6.30-2-amd64
Version: 2.6.30-8squeeze1
Severity: important
I have a server with some ethernet interfaces, and it's routing between
them:
02:00.0 Ethernet controller: Mellanox Technologies MT25448 [ConnectX EN 10GigE,
PCIe 2.0 2.5GT/s] (rev a0)
03:00.0 Ethernet controller: Mellanox Technologies MT25448 [ConnectX EN 10GigE,
PCIe 2.0 2.5GT/s] (rev a0)
05:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection
(rev 01)
05:00.1 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection
(rev 01)
Traffic flows between the 10g cards and the 1g card (only one of them is
used at this time), and from time to time I get a panic just like in the
subject line.
I've upgraded from the lenny kernel because oopses were much more frequent
with that (in fact, I could cause one with disabling tx checksumming on
the igb card and then routing 1 packet through the box (mlx4_en->igb)). I
don't know if this is related to the issue at hand, but I'm attaching the
log from that oops as well.
Best regards,
Matyas Koszik
