https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=210801 Bug ID: 210801 Summary: [panic] Fatral trap 12: page fault while in kernel mode (new in 11.0-ALPHA6 from 11.0-ALPHA3) Product: Base System Version: 11.0-CURRENT Hardware: Any OS: Any Status: New Keywords: regression Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: junovitch@freebsd.org CC: jhb@FreeBSD.org, kib@FreeBSD.org Possible regression between ALPHA3 and ALPHA6. It's happened randomly while doing some Poudriere runs and going back and forth at the console testing ports. Sadly I do not have a replication case just yet but have had two panics since updating Friday. - Before FreeBSD 11.0-ALPHA3 #0 r301817M: Sat Jun 11 08:34:23 UTC 2016 - After FreeBSD 11.0-ALPHA6 #0 r302303M: Fri Jul 1 04:55:24 UTC 2016 - Changes for the 'M' M share/man/man4/coretemp.4 M sys/dev/coretemp/coretemp.c - Excerpt from core: ... #0 doadump (textdump=0) at pcpu.h:221 221 pcpu.h: No such file or directory. in pcpu.h (kgdb) #0 doadump (textdump=0) at pcpu.h:221 #1 0xffffffff8039beab in db_dump (dummy=<value optimized out>, dummy2=false, dummy3=0, dummy4=0x0) at /usr/src/head/sys/ddb/db_command.c:533 #2 0xffffffff8039bca9 in db_command (cmd_table=<value optimized out>) at /usr/src/head/sys/ddb/db_command.c:440 #3 0xffffffff8039ba04 in db_command_loop () at /usr/src/head/sys/ddb/db_command.c:493 #4 0xffffffff8039e9eb in db_trap (type=<value optimized out>, code=<value optimized out>) at /usr/src/head/sys/ddb/db_main.c:251 #5 0xffffffff80b323d3 in kdb_trap (type=<value optimized out>, code=<value optimized out>, tf=<value optimized out>) at /usr/src/head/sys/kern/subr_kdb.c:654 #6 0xffffffff80fd52d1 in trap_fatal (frame=0xfffffe0469f087e0, eva=1036) at /usr/src/head/sys/amd64/amd64/trap.c:836 #7 0xffffffff80fd5503 in trap_pfault (frame=0xfffffe0469f087e0, usermode=0) at /usr/src/head/sys/amd64/amd64/trap.c:691 #8 0xffffffff80fd4aac in trap (frame=0xfffffe0469f087e0) at /usr/src/head/sys/amd64/amd64/trap.c:442 #9 0xffffffff80fb7ba1 in calltrap () at /usr/src/head/sys/amd64/amd64/exception.S:236 #10 0xffffffff80a9164c in filt_proc (kn=0xfffff800918b6900, hint=<value optimized out>) at /usr/src/head/sys/kern/kern_event.c:473 #11 0xffffffff80a8fbad in knote (list=<value optimized out>, hint=2147483648, lockflags=<value optimized out>) at /usr/src/head/sys/kern/kern_event.c:2045 #12 0xffffffff80a96dad in exit1 (td=0xfffff8023875a000, rval=184783104, signo=0) at /usr/src/head/sys/kern/kern_exit.c:515 #13 0xffffffff80a95ddd in sys_sys_exit (td=0xfffff800918b6900, uap=<value optimized out>) at /usr/src/head/sys/kern/kern_exit.c:178 #14 0xffffffff80fd5c6e in amd64_syscall (td=<value optimized out>, traced=0) at subr_syscall.c:135 #15 0xffffffff80fb7e8b in Xfast_syscall () at /usr/src/head/sys/amd64/amd64/exception.S:396 #16 0x000000080092a8ca in ??
