https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220358 --- Comment #11 from iz-rpi03@hs-karlsruhe.de --- I can add to this, that a 32-bit ARM (Raspberrr-PI) kernel r320571 panics immediately when a ssh connect is attempted. This behaviour is repeatable (3 panics out of 3 attempts). Just for the record: login: panic: Undefined instruction in kernel. time = 1499024534 KDB: stack backtrace: $a.6() at $a.6 pc = 0xc05fe050 lr = 0xc01577b0 (db_trace_self_wrapper+0x30) sp = 0xdc65a818 fp = 0xdc65a930 db_trace_self_wrapper() at db_trace_self_wrapper+0x30 pc = 0xc01577b0 lr = 0xc02f9130 (vpanic+0xc0) sp = 0xdc65a938 fp = 0xdc65a958 r4 = 0x00000100 r5 = 0xdc65a96c r6 = 0xc061b004 r7 = 0x00000001 vpanic() at vpanic+0xc0 pc = 0xc02f9130 lr = 0xc02f9070 (vpanic) sp = 0xdc65a960 fp = 0xdc65a964 r4 = 0x00000000 r5 = 0x00000000 r6 = 0x00000010 r7 = 0xffffff80 r8 = 0xdc65a9f0 r9 = 0x00000001 r10 = 0xc2caafdc vpanic() at vpanic pc = 0xc02f9070 lr = 0xc061afec ($d.14) sp = 0xdc65a96c fp = 0xdc65a9e8 r4 = 0xffffff80 r5 = 0xdc65a9f0 r6 = 0x00000001 r7 = 0xc2caafdc r8 = 0xdc65a964 r9 = 0xc02f9070 r10 = 0xdc65a96c $d.14() at $d.14 pc = 0xc061afec lr = 0xc0600b94 (exception_exit) sp = 0xdc65a9f0 fp = 0xdc65aa88 r4 = 0xa0000013 r5 = 0xc2caaa78 r6 = 0x00000010 r7 = 0xc2bd4700 r8 = 0xc2c51824 r9 = 0xc2caa430 r10 = 0x00000000 exception_exit() at exception_exit pc = 0xc0600b94 lr = 0xc0389544 (solisten_wakeup+0x28) sp = 0xdc65aa80 fp = 0xdc65aa88 r0 = 0xc2caaa78 r1 = 0x00000000 r2 = 0x00000001 r3 = 0xc2caaa90 r4 = 0x00000001 r5 = 0xc2caaa78 r6 = 0x00000010 r7 = 0xc2bd4700 r8 = 0xc2c51824 r9 = 0xc2caa430 r10 = 0x00000000 r12 = 0x00000000 _end() at 0xc2caafdc pc = 0xc2caafdc lr = 0xc0389544 (solisten_wakeup+0x28) sp = 0xdc65aa80 fp = 0xdc65aa88 KDB: enter: panic [ thread pid 13 tid 100033 ] Stopped at $d.12: ldrb r15, [r15, r15, ror r15]! db> db> show proc Process 13 (usb) at 0xc288a398: state: NORMAL uid: 0 gids: 0 parent: pid 0 at 0xc0783548 ABI: null threads: 6 100031 D - 0xc291b02c [usbus0] 100032 D - 0xc291b05c [usbus0] 100033 Run CPU 0 [usbus0] 100034 D - 0xc291b0bc [usbus0] 100035 D - 0xc291b0ec [usbus0] 100069 D - 0xc2a9da28 [smsc0] db> show thread Thread 100033 at 0xc2936000: proc (pid 13): 0xc288a398 name: usbus0 stack: 0xdc659000-0xdc65afff flags: 0x1000004 pflags: 0x200000 state: RUNNING (CPU 0) priority: 28 container lock: sched lock (0xc07713c4) last voluntary switch: 1 ms ago last involuntary switch: 0 ms ago db> -- You are receiving this mail because: You are the assignee for the bug.
