Unable to handle kernel paging request at ffffc200000fb000 RIP:
[<ffffffff8031b8f0>] deflate_slow+0x40/0x400
Here is some more information about the scenario in which I can easily
reproduce the oops now:
Net_A - GW_A --- GW_B - Net_B
The Net_A - Net_B ESP/AES/IPComp tunnel works fine, the tunnel between
Net_B and the external IP address of GW_A triggers the oops in GW_A.

OK, so are you now able to reproduce this crash without waiting
for hours? That would be really helpful in tracking it down.
Yes, I can reproduce it in minutes now.
Could you show me the exact policies/SAs of the tunnel involved
in the crash?

No I meant the exact output of ip x p and ip x s.
I know, but as I end up every time with a tainted kernel on our
production server I didn't turn ipcomp on, but now I got it.
