Very sorry for being late, just i found way to stabilize kernel for me and to 
solve my personal life issues. It took 2 weeks...
I will try this patch, but i'm sure i dont have multiqueue card there.

I had shaper on eth0.33 and eth0 so i disable all offloading except 
checksumming there. Recently i found  that on some interfaces (where is no 
shaper) gso left on. And yes, probably some traffic was queued, then route 
changed, and maybe it went from gso off interface to gso on... 
It can be just pure luck, that i dont have crashes anymore, but maybe trick is 
in gso...
