Hi, this panic has been reported a few times in the past, both by me and other people; I just updated my Soekris box to 6.2-RC2 and it's still happening. panic: bus_dmamap_load_mbuf_sg: no mbuf packet header! KDB: stack backtrace: panic(c06128c3,c060f93c,c055b9af,c0db804e,c0db803e,...) at panic+0xef bus_dmamap_load_mbuf_sg(c0d18e00,0,c0db8000,c0d627d8,c0d627b8,1) at bus_dmamap_load_mbuf_sg+0x4ec ath_start(c0d55000,35000,36,0,c1000000,...) at ath_start+0x26f ether_output_frame(c0d55000,c0fee600,c1000006,0,1,...) at ether_output_frame+0x226 ether_output(c0d55000,c0fee600,c56f6bb0,c0feb840) at ether_output+0x2de ip_output(c0fee600,0,c56f6bac,1,0,0) at ip_output+0xaad ip_forward(c0cf9648,c56f6c78,c04e14dd,c066ca40,1,...) at ip_forward+0x120 ip_input(c0fee600,18,c0673378,c56f6cec,c0541fd7,...) at ip_input+0x8d5 netisr_processqueue(c0d12240,c0cef400,0,c56f6d0c,c04bd93b,...) at netisr_processqueue+0x13 swi_net(0,c0cef438,c0cfaa80,c04bd740,c0cf9648,...) at swi_net+0x97 ithread_loop(c0ce8750,c56f6d38,c0ce8750,c04bd740,0,...) at ithread_loop+0x1fb fork_exit(c04bd740,c0ce8750,c56f6d38) at fork_exit+0x83 fork_trampoline() at fork_trampoline+0x8 --- trap 0x1, eip = 0, esp = 0xc56f6d6c, ebp = 0 --- KDB: enter: panic [thread pid 13 tid 100003 ] Stopped at kdb_enter+0x2c: leal 0(%esi),%esi It has been suggested that it may be pf-related, but I don't have a clue on how to go about digging more info out. Any idea? Bye, Andrea -- If it's there, and you can see it, it's real. If it's not there, and you can see it, it's virtual. If it's there, and you can't see it, it's transparent. If it's not there, and you can't see it, you erased it.
