Kernel Panic with bonding + IPoIB on 3.2.9
From: Joseph Glanville
Date: Sun Mar 18 2012 - 15:48:32 EST
Hi guys,
I am getting an annoying kernel panic on 3.2.9 that seems to be
related to bonding (as I can't reproduce the crash without it)
I believe it might be related to LRO/GRO but there isnt a param to
disable it anymore that I could see in /ulp/ipoib/
Let me know if there is anything further I can do to help debug.
Useful information:
