$ lsmod | grep "[^0-9]0" | grepbyhand
ip_gre                 16865  0
3c59x                  41213  0
tg3                    85061  0

It is very likely an error that these have usage counts of 0.
(the interfaces are very much up, and a GRE tunnel is configured)
Seeing as the same thing happens with bcm5700 modules from HP it's likely 
this is not actually a module problem but a more basic networking 
logic fault.

I can't test whether removing tg3/3c59x will result in a panic, but 
removing the ip_gre module broke the system (praise ilo...) - Not posting 
a trace since it's obvious why it broke...

Comments?
