Please: If you have a kernel dump, load it in gdb (https://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug-gdb.html): # cd /usr/obj/usr/src/sys/<YOUR KERNCONF> # kgdb kernel.debug /var/crash/vmcore.<YOUR KERNELDUMP NUMBER> <YOUR KERNELDUMP NUMBER> is printed on first boot after panic. than make stack backtrace (kgdb) bt #0 __curthread () at ./machine/pcpu.h:225 #1 doadump (textdump=0) at /usr/src/sys/kern/kern_shutdown.c:318 #2 0xc057940e in db_dump (dummy=-1060412150, dummy2=<error reading variable: access outside bounds of object referenced via synthetic pointer>, dummy3=-1, dummy4=0xee9cb90c "") at /usr/src/sys/ddb/db_command.c:572 #3 0xc05791e1 in db_command (last_cmdp=<optimized out>, cmd_table=<optimized out>, dopager=<optimized out>) at /usr/src/sys/ddb/db_command.c:479 #4 0xc0578f40 in db_command_loop () at /usr/src/sys/ddb/db_command.c:532 #5 0xc057bfea in db_trap (type=<optimized out>, code=<optimized out>) at /usr/src/sys/ddb/db_main.c:248 #6 0xc0cb6cbe in kdb_trap (type=<optimized out>, code=<optimized out>, tf=0xee9cbb7c) at /usr/src/sys/kern/subr_kdb.c:654 #7 0xc12282cd in trap (frame=<optimized out>) at /usr/src/sys/i386/i386/trap.c:680 #8 <signal handler called> #9 kdb_enter (why=0xc162ab65 "panic", msg=<optimized out>) at /usr/src/sys/kern/subr_kdb.c:444 #10 0xc0c709b0 in vpanic (fmt=<optimized out>, ap=<optimized out>) at /usr/src/sys/kern/kern_shutdown.c:772 #11 0xc0c709eb in panic (fmt=0xc1628b04 "1") at /usr/src/sys/kern/kern_shutdown.c:710 #12 0xc112dbb9 in psmintr (arg=0xc7c0e000) at /usr/src/sys/dev/atkbdc/psm.c:2954 #13 0xc0c31bbe in intr_event_execute_handlers (p=0xee9cbcac, ie=<optimized out>) at /usr/src/sys/kern/kern_intr.c:1336 #14 0xc0c321d0 in ithread_execute_handlers (ie=<optimized out>, p=<optimized out>) at /usr/src/sys/kern/kern_intr.c:1349 #15 ithread_loop (arg=0xc6ef1ef0) at /usr/src/sys/kern/kern_intr.c:1430 #16 0xc0c2edfe in fork_exit (callout=0xc0c32130 <ithread_loop>, arg=<optimized out>, frame=<optimized out>) at /usr/src/sys/kern/kern_fork.c:1044 #17 <signal handler called> Than find a frame with psmintr().
