Re: [B.A.T.M.A.N.] kernel BUG at net/core/skbuff.c:100

Hi Martin, hi all.

Should I keep on reporting? Meanwhile I'm running out of space for the vmcore dumps. Is it me, is it the kernel or is it Batman-adv? What should I do? Should I bother the kernel hackers?

This bug happened 44 minutes after changing gw client to gw server.

Best regards

Philipp
