https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217413 --- Comment #1 from bsd@kobyla.org --- System was updated to the fresh HEAD. For testing purposes 2 ports were set to ifconfig down (media: Ethernet autoselect) and directly connected by a patch-cord: kernel: bce2: Gigabit link up! kernel: bce2: link state changed to UP kernel: bce3: Gigabit link up! kernel: bce3: link state changed to UP No problem yet. Immediately after patch-cord disconnection links state change and server panics. So link disconnection also brings the same problem: kernel: bce2: link state changed to DOWN kernel: bce3: link state changed to DOWN Dump header from device: /dev/mfid0p20 Architecture: amd64 Architecture Version: 2 Dump Length: 2216656896 Blocksize: 512 Dumptime: Tue Feb 28 13:28:00 2017 Hostname: dell1.home Magic: FreeBSD Kernel Dump Version String: FreeBSD 12.0-CURRENT #0 r314382M: Tue Feb 28 13:03:43 UTC 2017 root@dell1.home:/usr/obj/usr/src/sys/PDC10 Panic String: Assertion err =3D=3D 0 failed at /usr/src/sys/net/iflib.c:2= 242 Dump Parity: 2816930518 Bounds: 6 Dump Status: good #0 doadump (textdump=3D0) at pcpu.h:232 232 pcpu.h: No such file or directory. in pcpu.h (kgdb) #0 doadump (textdump=3D0) at pcpu.h:232 #1 0xffffffff8031d0fc in db_fncall (dummy1=3D<value optimized out>,=20 dummy2=3D<value optimized out>, dummy3=3D<value optimized out>,=20 dummy4=3D<value optimized out>) at /usr/src/sys/ddb/db_command.c:581 #2 0xffffffff8031cc7f in db_command (cmd_table=3D<value optimized out>) at /usr/src/sys/ddb/db_command.c:453 #3 0xffffffff80321648 in db_script_exec (scriptname=3D<value optimized ou= t>,=20 warnifnotfound=3D<value optimized out>) at /usr/src/sys/ddb/db_script.= c:302 #4 0xffffffff80321493 in db_script_kdbenter (eventname=3D<value optimized= out>) at /usr/src/sys/ddb/db_script.c:324 #5 0xffffffff8031f9aa in db_trap (type=3D<value optimized out>,=20 code=3D<value optimized out>) at /usr/src/sys/ddb/db_main.c:247 #6 0xffffffff80583983 in kdb_trap (type=3D<value optimized out>,=20 code=3D<value optimized out>, tf=3D<value optimized out>) at /usr/src/sys/kern/subr_kdb.c:654 #7 0xffffffff8082b601 in trap (frame=3D0xfffffe044117f890) at /usr/src/sys/amd64/amd64/trap.c:537 #8 0xffffffff8080dca1 in calltrap () at /usr/src/sys/amd64/amd64/exception.S:236 #9 0xffffffff805830ab in kdb_enter (why=3D0xffffffff80932ea1 "panic",=20 msg=3D<value optimized out>) at cpufunc.h:63 #10 0xffffffff80543003 in vpanic (fmt=3D<value optimized out>,=20 ap=3D0xfffffe044117fa20) at /usr/src/sys/kern/kern_shutdown.c:772 #11 0xffffffff80542e56 in kassert_panic (fmt=3D<value optimized out>) at /usr/src/sys/kern/kern_shutdown.c:669 #12 0xffffffff8064134f in _task_fn_rx (context=3D<value optimized out>) at /usr/src/sys/net/iflib.c:2242 #13 0xffffffff80581e59 in gtaskqueue_run_locked (queue=3D<value optimized = out>) at /usr/src/sys/kern/subr_gtaskqueue.c:327 #14 0xffffffff80581be8 in gtaskqueue_thread_loop (arg=3D<value optimized o= ut>) at /usr/src/sys/kern/subr_gtaskqueue.c:502 #15 0xffffffff805080b4 in fork_exit ( callout=3D0xffffffff80581b60 <gtaskqueue_thread_loop>,=20 arg=3D0xfffffe00010e3080, frame=3D0xfffffe044117fc00) at /usr/src/sys/kern/kern_fork.c:1038 #16 0xffffffff8080e1de in fork_trampoline () at /usr/src/sys/amd64/amd64/exception.S:611 #17 0x0000000000000000 in ??
