Synopsis: [bce] [panic] kernel panic in bce0 driver State-Changed-From-To: open->feedback State-Changed-By: yongari State-Changed-When: Mon Dec 12 19:26:05 UTC 2011 State-Changed-Why: As you see, this backtrace looks wrong. It can't generate a NULL pointer dereference at line 5771. Are you using stock bce(4) without any changes? Probably the m0 could be a NULL and it could be dereferenced later. Could you go frame 8 and do the following? p m0 p sw_rx_cons_idx p sc->rx_mbuf_ptr[sw_rx_cons_idx] By chance, did the panic happen when you reboot your box or down/up the interface? Or if you happen to know a way to reproduce the issue could you share it with us?
