8-stable panics in igb(8)

[Maxim Sobolev]

Hi,

We have observed what appears to be a crash in the interrupt thread for 
the igb(8) driver on one of our systems. This machine runs May 22's 
8.2-STABLE. For some reason the IP of the crash (0xffffffff806d6399) 
points to the key_sendup0() function, however we never had IPsec 
configured on that box, so I suspect it is not accurate.

Any ideas of what could be wrong there are appreciated.

Thanks!
