I'm getting a panic and an error message (xn_txeof: WARNING: response is -1) when I try to use ssh (the error also show for other network operation but not the panic) Here goes the panic I get after I try ssh: xn_txeof: WARNING: response is -1! panic: mbuf already on the free list, but we're trying to free it again! cpuid = 0 KDB: enter: panic [ thread pid 12 tid 100026 ] Stopped at kdb_enter+0x3e: movq $0,kdb_why db> bt Tracing pid 12 tid 100026 td 0xfffffe000be79920 kdb_enter() at kdb_enter+0x3e/frame 0xffffff80002fe8c0 vpanic() at vpanic+0x146/frame 0xffffff80002fe900 kassert_panic() at kassert_panic+0x136/frame 0xffffff80002fe970 xn_txeof() at xn_txeof+0x99/frame 0xffffff80002fe9c0 xn_intr() at xn_intr+0x59/frame 0xffffff80002feab0 evtchn_interrupt() at evtchn_interrupt+0x1e6/frame 0xffffff80002feb30 intr_event_execute_handlers() at intr_event_execute_handlers+0x90/frame 0xffffff80002feb70 ithread_loop() at ithread_loop+0x148/frame 0xffffff80002febb0 fork_exit() at fork_exit+0x84/frame 0xffffff80002febf0 fork_trampoline() at fork_trampoline+0xe/frame 0xffffff80002febf0 --- trap 0, rip = 0, rsp = 0xffffff80002fecb0, rbp = 0 --- I've tried a few revisions and actually revert way back to the last one that was working on 9.x which in stable/10 would be Revision 251297 but no luck. So probably the issue is somewhere else then netfront, but I have no idea where to look next. If anyone has a netbsd dom0 that could test this would be much appreciated... I'm using NetBSD 6.1.2 btw
