Subject: BUG: skb_under_panic in eth_header (3.0.34)
Bug report from sysop@...sjakt.nu
It is a skb_under_panic in eth_header where it trying to make space for
the Ethernet header?
https://bugzilla.kernel.org/show_bug.cgi?id=42764
I got it one more time. Ethernet card is:
0e:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709S Gigabit
Ethernet (rev 20)
ethtool -i eth0
driver: bnx2
version: 2.1.6
firmware-version: bc 4.4.14 IPMI 0.1.16
bus-info: 0000:04:00.0
ethtool -i eth2
driver: bnx2
version: 2.1.6
firmware-version: bc 4.4.10
bus-info: 0000:0e:00.0
Could this be related to an old firmware?
This machine does a lot of network traffic, because it load data from a
database every night.
Kernel version is 3.0.34
Sorry for not reporting hardware, I thought it was a protocol bug not related
to a specific card.
