^^^^^^^^^^^^^
edi is NULL and it means that the (struct sock *) sk that take as
parameter __release_sock() is NULL too. It' s a bit strange that the first
dereferencing of the NULL pointer don' t generate a trap (really the
kernel is not dereferencing NULL but NULL+something). Then at the location
NULL+something there is garbage and dereferencing garbage you got the
Oops.
This patch should avoid the Oops, but it' s not the fix, the bug is still
somewhere (I really don' t know where ;-).
Patch against 0.34.
