--0000000000000006c705ef534af8 Content-Type: text/plain; charset="UTF-8" Hi folks -- I opened this on Freebsd 13.1. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268246 I'm stumped, as I have about half a dozen other systems just like this one, which do not exhibit this condition. Don't know if it matters, but this is the backup firewall in a carp configuration. kgdb /usr/lib/debug/boot/kernel/kernel.debug /var/crash/vmcore.0 Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0x18 fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff80cadb90 stack pointer = 0x28:0xfffffe0204794bc0 frame pointer = 0x28:0xfffffe0204794c20 code segment = base r <https://svnweb.freebsd.org/changeset/base/>x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 12 (swi1: pfsync) trap number = 12 panic: page fault cpuid = 0 time = 1670433489 KDB: stack backtrace: #0 0xffffffff80c694a5 at kdb_backtrace+0x65 #1 0xffffffff80c1bb5f at vpanic+0x17f #2 0xffffffff80c1b9d3 at panic+0x43 #3 0xffffffff810afdf5 at trap_fatal+0x385 #4 0xffffffff810afe4f at trap_pfault+0x4f #5 0xffffffff810875b8 at calltrap+0x8 #6 0xffffffff80dca82f at ip_fragment+0x24f #7 0xffffffff80dca1e3 at ip_output+0x1163 #8 0xffffffff8225a851 at pfsyncintr+0x151 #9 0xffffffff80bdbcfa at ithread_loop+0x25a #10 0xffffffff80bd8a9e at fork_exit+0x7e #11 0xffffffff8108862e at fork_trampoline+0xe Uptime: 43m36s Dumping 7356 out of 130983 MB:..1%..11%..21%..31%..41%..51%..61%..71%..81%..91% --0000000000000006c705ef534af8 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr"><div>Hi folks -- I opened this on Freebsd 13.1.</div><div>= <br></div><div><a href=3D"https://bugs.freebsd.org/bugzilla/show_bug.cgi?id= =3D268246">https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D268246</a></= div><div><br></div><div>I'm stumped, as I have about half a dozen other= systems just like this one, which do not exhibit this condition. <br></div= ><div><br></div><div>Don't know if it matters, but this is the backup f= irewall in a carp configuration. <br></div><div><br></div><div><br></div><d= iv>kgdb /usr/lib/debug/boot/kernel/kernel.debug /var/crash/vmcore.0 <pre class=3D"gmail-bz_comment_text" id=3D"gmail-comment_text_0" style=3D"f= ont-size:small;font-family:monospace;white-space:pre-wrap;width:50em;paddin= g-left:0.5em;padding-right:0.5em;color:rgb(0,0,0);font-style:normal;font-va= riant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spac= ing:normal;text-align:start;text-indent:0px;text-transform:none;word-spacin= g:0px;background-color:rgb(255,255,255);text-decoration-style:initial;text-= decoration-color:initial">Fatal trap 12: page fault while in kernel mode cpuid =3D 0; apic id =3D 00 fault virtual address =3D 0x18 fault code =3D supervisor read data, page not present instruction pointer =3D 0x20:0xffffffff80cadb90 stack pointer =3D 0x28:0xfffffe0204794bc0 frame pointer =3D 0x28:0xfffffe0204794c20 code segment =3D <a href=3D"https://svnweb.freebsd.org/changeset= /base/" title=3D"revision in base" style=3D"color:rgb(153,0,0)">base r</a>= x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 12 (swi1: pfsync) trap number =3D 12 panic: page fault cpuid =3D 0 time =3D 1670433489 KDB: stack backtrace: #0 0xffffffff80c694a5 at kdb_backtrace+0x65 #1 0xffffffff80c1bb5f at vpanic+0x17f #2 0xffffffff80c1b9d3 at panic+0x43 #3 0xffffffff810afdf5 at trap_fatal+0x385 #4 0xffffffff810afe4f at trap_pfault+0x4f #5 0xffffffff810875b8 at calltrap+0x8 #6 0xffffffff80dca82f at ip_fragment+0x24f #7 0xffffffff80dca1e3 at ip_output+0x1163 #8 0xffffffff8225a851 at pfsyncintr+0x151 #9 0xffffffff80bdbcfa at ithread_loop+0x25a #10 0xffffffff80bd8a9e at fork_exit+0x7e #11 0xffffffff8108862e at fork_trampoline+0xe Uptime: 43m36s Dumping 7356 out of 130983 MB:..1%..11%..21%..31%..41%..51%..61%..71%..81%.= .91%</pre> </div></div> --0000000000000006c705ef534af8--
