New submission from Ralf Schmitt <r...@systemexit.de>: I'm getting a kernel panic if I remove the network cable and plug it in again. I'm running dhclient on this machine and if I turn it off I can unplug the network cable and plug it in again without getting a kernel panic.
crash dump is available here: http://systemexit.de/dragonfly-crash-network-cable-remove/crash.tgz it gives me the following backtrace (looks like some routing information should is being updated): (kgdb) bt #0 _get_mycpu (di=<value optimized out>) at ./machine/thread.h:69 #1 md_dumpsys (di=<value optimized out>) at /usr/src/sys/platform/pc64/x86_64/dump_machdep.c:263 #2 0xffffffff8047e8d5 in dumpsys () at /usr/src/sys/kern/kern_shutdown.c:927 #3 0xffffffff8029a3dc in db_fncall (dummy1=<value optimized out>, dummy2=<value optimized out>, dummy3=<value optimized out>, dummy4=<value optimized out>) at /usr/src/sys/ddb/db_command.c:542 #4 0xffffffff8029a8af in db_command () at /usr/src/sys/ddb/db_command.c:344 #5 db_command_loop () at /usr/src/sys/ddb/db_command.c:470 #6 0xffffffff8029d761 in db_trap (type=<value optimized out>, code=<value optimized out>) at /usr/src/sys/ddb/db_trap.c:71 #7 0xffffffff8071e238 in kdb_trap (type=<value optimized out>, code=<value optimized out>, regs=<value optimized out>) at /usr/src/sys/platform/pc64/x86_64/db_interface.c:176 #8 0xffffffff80723d66 in trap (frame=0xffffffe08d6f3aa8) at /usr/src/sys/platform/pc64/x86_64/trap.c:701 #9 0xffffffff8071c77e in calltrap () at /usr/src/sys/platform/pc64/x86_64/exception.S:187 #10 0xffffffff8071e0cf in breakpoint (msg=<value optimized out>) at ./cpu/cpufunc.h:73 #11 Debugger (msg=<value optimized out>) at /usr/src/sys/platform/pc64/x86_64/db_interface.c:361 #12 0xffffffff8047f1c4 in panic ( fmt=0xffffffff807cf400 "rtrequest1_msghandler: rtrequest table error was not on cpu #0") at /usr/src/sys/kern/kern_shutdown.c:824 #13 0xffffffff80525eb9 in rtrequest1_msghandler (msg=<value optimized out>) at /usr/src/sys/net/route.c:812 #14 0xffffffff805250c0 in rtable_service_loop (dummy=<value optimized out>) at /usr/src/sys/net/route.c:202 #15 0xffffffff80489acf in lwkt_deschedule_self (td=0x0) at /usr/src/sys/kern/lwkt_thread.c:283 Backtrace stopped: previous frame inner to this frame (corrupt stack?) ---------- keyword: kernel, x86-64 messages: 10083 nosy: schmir priority: critical status: unread title: kernel panic when removing the network cable _____________________________________________________ DragonFly issue tracker <b...@lists.dragonflybsd.org> <http://bugs.dragonflybsd.org/issue2126> _____________________________________________________
