Thanks for the quick reply.
It’s beginning to look like “something like that”…
io-net appears to be crashing in a call to m_free (I say “appears” because
the core file is somehow corrupt - can’t get more than a couple of frames
Anyway, this seems to be after the packet leaves our driver.
Any ideas/hints/clues as to how to track this down greatly appreciated.

It has been suggested that the io-net alloc and free functions are not
re-entrant, and our use of them needs to be protected by mutex.
No, if you stick with the “alloc()”, “alloc_up_pkt()”, “alloc_down_pkt()”,
they are all protected (by an internal mutex).
The only bad thing could happen is you double freed or sth like that.
