(Editing the subject line, because this report is not yet found via the bug search button at the FreshPorts page.) > the bug search button at the FreshPorts page Sorry, now I see: the preset search criteria include 'Product: Ports & Packages' and 'Component: Individual Port(s)', so a kernel bug should never be found by such searches. Need to triage bug 268848, change its product. See also: <https://codeberg.org/grahamperrin/freebsd-src/issues/2> > … www/chromium (Chromium): panic: general protection fault with > chrome as the current process … Now, I wonder whether Control-Q (in the summary line here) was truly the key combination that I used on 5th September. |
Dump header from device: /dev/ada0p2 Architecture: amd64 Architecture Version: 2 Dump Length: 2269585408 Blocksize: 512 Compression: none Dumptime: 2023-09-05 13:09:49 +0100 Hostname: mowa219-gjp4-8570p-freebsd Magic: FreeBSD Kernel Dump Version String: FreeBSD 15.0-CURRENT amd64 1500000 #10 main-n265135-07bc20e4740d-dirty: Sat Sep 2 17:36:59 BST 2023 grahamperrin@mowa219-gjp4-8570p-freebsd:/usr/obj/usr/src/amd64.amd64/sys/GENERIC Panic String: general protection fault Dump Parity: 3731071829 Bounds: 0 Dump Status: good ---- If I recall correctly: at the moment of the panic I was moving the pointer, or typing, in Remmina (an RDP connection to Windows) or Firefox. I might have also keyed Alt-Tab to switch applications after the Control-Q. I assumed that quit of Chromium was complete, however PID 50768 (chrome) is shown, below, as the current process. I'll send panicmail with reference to this bug report. --- Unread portion of the kernel message buffer: Fatal trap 9: general protection fault while in kernel mode cpuid = 0; apic id = 00 instruction pointer = 0x20:0xffffffff80d280b0 stack pointer = 0x28:0xfffffe01030ccb20 frame pointer = 0x28:0xfffffe01030ccb40 code segment = base rx0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 50768 (chrome) rdi: deadc0dedeadc0de rsi: 0000000000000001 rdx: 0000000000000000 rcx: fffff8028bc4c560 r8: fffff800018cf040 r9: fffffe01030cd000 rax: fffff8028bc4c500 rbx: fffff802b285b500 rbp: fffffe01030ccb40 r10: 0000000000001388 r11: 00000000000027a7 r12: fffff8028bc4c500 r13: fffff801efef5640 r14: fffff802b285b500 r15: fffff801efef5660 trap number = 9 panic: general protection fault cpuid = 3 time = 1693915789 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe01030cc860 vpanic() at vpanic+0x132/frame 0xfffffe01030cc990 panic() at panic+0x43/frame 0xfffffe01030cc9f0 trap_fatal() at trap_fatal+0x40c/frame 0xfffffe01030cca50 calltrap() at calltrap+0x8/frame 0xfffffe01030cca50 --- trap 0x9, rip = 0xffffffff80d280b0, rsp = 0xfffffe01030ccb20, rbp = 0xfffffe01030ccb40 --- ip_mfilter_free() at ip_mfilter_free+0x1a0/frame 0xfffffe01030ccb40 inp_freemoptions() at inp_freemoptions+0x85/frame 0xfffffe01030ccb80 sorele_locked() at sorele_locked+0xf7/frame 0xfffffe01030ccbb0 soclose() at soclose+0x17d/frame 0xfffffe01030ccc10 _fdrop() at _fdrop+0x1b/frame 0xfffffe01030ccc30 closef() at closef+0x1e3/frame 0xfffffe01030cccc0 fdescfree() at fdescfree+0x41a/frame 0xfffffe01030ccd80 exit1() at exit1+0x4b1/frame 0xfffffe01030ccdf0 sys_exit() at sys_exit+0xd/frame 0xfffffe01030cce00 amd64_syscall() at amd64_syscall+0x138/frame 0xfffffe01030ccf30 fast_syscall_common() at fast_syscall_common+0xf8/frame 0xfffffe01030ccf30 --- syscall (1, FreeBSD ELF64, exit), rip = 0x2f6f91df251a, rsp = 0x2f6f6517bd28, rbp = 0x2f6f6517bd40 --- KDB: enter: panic Uptime: 1d2h13m47s Dumping 2164 out of 16244 MB:..1%..11%..21%..31%..41%..51%..61%..71%..81%..91% __curthread () at /usr/src/sys/amd64/include/pcpu_aux.h:57 57 __asm("movq %%gs:%P1,%0" : "=r" (td) : "n" (offsetof(struct pcpu, (kgdb) #0 __curthread () at /usr/src/sys/amd64/include/pcpu_aux.h:57 #1 doadump (textdump=textdump@entry=1) at /usr/src/sys/kern/kern_shutdown.c:405 #2 0xffffffff80b57f60 in kern_reboot (howto=260) at /usr/src/sys/kern/kern_shutdown.c:526 #3 0xffffffff80b5845f in vpanic (fmt=0xffffffff811a0789 "%s", ap=ap@entry=0xfffffe01030cc9d0) at /usr/src/sys/kern/kern_shutdown.c:970 #4 0xffffffff80b58203 in panic (fmt=<unavailable>) at /usr/src/sys/kern/kern_shutdown.c:894 #5 0xffffffff8105dd7c in trap_fatal (frame=0xfffffe01030cca60, eva=0) at /usr/src/sys/amd64/amd64/trap.c:952 #6 <signal handler called> #7 mbufq_drain (mq=<optimized out>) at /usr/src/sys/sys/mbuf.h:1593 #8 imf_purge (imf=imf@entry=0xfffff802b285b500) at /usr/src/sys/netinet/in_mcast.c:919 #9 ip_mfilter_free (imf=imf@entry=0xfffff802b285b500) at /usr/src/sys/netinet/in_mcast.c:350 #10 0xffffffff80d29455 in inp_freemoptions (imo=0xfffff801efef5640) at /usr/src/sys/netinet/in_mcast.c:1610 #11 0xffffffff80c098d7 in sofree (so=0xfffff8040a4643c0) at /usr/src/sys/kern/uipc_socket.c:1211 #12 sorele_locked (so=so@entry=0xfffff8040a4643c0) at /usr/src/sys/kern/uipc_socket.c:1238 #13 0xffffffff80c0a74d in soclose (so=0xfffff8040a4643c0) at /usr/src/sys/kern/uipc_socket.c:1308 #14 0xffffffff80af232b in fo_close (fp=0xfffff803c7dd9d20, td=0x1) at /usr/src/sys/sys/file.h:388 #15 _fdrop (fp=fp@entry=0xfffff803c7dd9d20, td=0x1, td@entry=0xfffffe0104a20e40) at /usr/src/sys/kern/kern_descrip.c:3632 #16 0xffffffff80af5b83 in closef (fp=fp@entry=0xfffff803c7dd9d20, td=td@entry=0xfffffe0104a20e40) at /usr/src/sys/kern/kern_descrip.c:2841 #17 0xffffffff80af51ea in fdescfree_fds (td=0xfffffe0104a20e40, fdp=0xfffffe0104d7d920) at /usr/src/sys/kern/kern_descrip.c:2564 #18 fdescfree (td=td@entry=0xfffffe0104a20e40) at /usr/src/sys/kern/kern_descrip.c:2607 #19 0xffffffff80b07d81 in exit1 (td=0xfffffe0104a20e40, rval=<optimized out>, signo=signo@entry=0) at /usr/src/sys/kern/kern_exit.c:404 #20 0xffffffff80b078cd in sys_exit (td=0xdeadc0dedeadc0de, uap=<optimized out>) at /usr/src/sys/kern/kern_exit.c:210 #21 0xffffffff8105e748 in syscallenter (td=<optimized out>) at /usr/src/sys/amd64/amd64/../../kern/subr_syscall.c:187 #22 amd64_syscall (td=0xfffffe0104a20e40, traced=0) at /usr/src/sys/amd64/amd64/trap.c:1197 #23 <signal handler called> #24 0x00002f6f91df251a in ??
