Subject: skb_over_panic kernel panic

Hello,

I keep getting kernel panics on my system with output similar to this:

skb_over_panic: text:fffffffff80456cc4 len:2580 put:2580
head:ffff9900bf18a000 data:ffff8800bf18a010 tail:0xa end:0x640 dev:eth0

(I copied this output by hand so there may be a typo or two) 

Linux server1 2.6.28.7 #3 SMP Mon Mar 9 20:04:12 EDT 2009 x86_64
Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz GenuineIntel GNU/Linux

Before this my kernel was 2.6.27.5 and I was still getting the same
panics.
