https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D261233 Richard Frewin <Richard@FrewinIT.uk> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |Richard@FrewinIT.uk --- Comment #8 from Richard Frewin <Richard@FrewinIT.uk> --- Just a +1 for this. Upgraded from kernel 12.2-RELEASE-p7 to 12.2-RELEASE-p12 with freebsd-updat= e on several systems both amd64 and i386. Some of the i386 systems now panic un= der disk load (backups!). These are otherwise very lightly loaded web servers = or firewalls. Is this related to Bug 261338 ? Example panics from three systems (cut-and-paste from dmesg) below: Fatal trap 12: page fault while in kernel mode cpuid =3D 0; apic id =3D 00 fault virtual address =3D 0x0 fault code =3D supervisor read, page not present instruction pointer =3D 0x20:0x0 stack pointer =3D 0x28:0x1b2de880 frame pointer =3D 0x28:0x1b2de8bc code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, def32 1, gran 1 processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 836 (bacula-fd) trap number =3D 12 panic: page fault cpuid =3D 0 time =3D 1642636089 KDB: stack backtrace: #0 0x10327ae at kdb_backtrace+0x4e #1 0xfed128 at vpanic+0x118 #2 0xfed004 at panic+0x14 #3 0x154bfd5 at trap_fatal+0x335 #4 0x154c013 at trap_pfault+0x33 #5 0x154b71f at trap+0x36f #6 0xffc0319d at PTDpde+0x41a5 #7 0x1534905 at copyout+0xa5 #8 0x154d0f9 at uiomove_fromphys+0x159 #9 0x12c3483 at ffs_read+0x3d3 #10 0x157b77d at VOP_READ_APV+0x5d #11 0x10b980a at vn_read+0x18a #12 0x10b95da at vn_io_fault_doio+0x3a #13 0x10b7232 at vn_io_fault1+0x162 #14 0x10b548b at vn_io_fault+0x1cb #15 0x104c580 at dofileread+0x70 #16 0x104c1d8 at sys_read+0x78 #17 0x154c7b9 at syscall+0x3e9 Uptime: 23h37m45s Physical memory: 2009 MB Fatal trap 12: page fault while in kernel mode cpuid =3D 0; apic id =3D 00 fault virtual address =3D 0x0 fault code =3D supervisor read, page not present instruction pointer =3D 0x20:0x0 stack pointer =3D 0x28:0x1afd6880 frame pointer =3D 0x28:0x1afd68bc code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, def32 1, gran 1 processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 2134 (bacula-fd) trap number =3D 12 panic: page fault cpuid =3D 0 time =3D 1642547014 KDB: stack backtrace: #0 0x10327ae at kdb_backtrace+0x4e #1 0xfed128 at vpanic+0x118 #2 0xfed004 at panic+0x14 #3 0x154bfd5 at trap_fatal+0x335 #4 0x154c013 at trap_pfault+0x33 #5 0x154b71f at trap+0x36f #6 0xffc0319d at PTDpde+0x41a5 #7 0x1534905 at copyout+0xa5 #8 0x154d0f9 at uiomove_fromphys+0x159 #9 0x12c3483 at ffs_read+0x3d3 #10 0x157b77d at VOP_READ_APV+0x5d #11 0x10b980a at vn_read+0x18a #12 0x10b95da at vn_io_fault_doio+0x3a #13 0x10b7232 at vn_io_fault1+0x162 #14 0x10b548b at vn_io_fault+0x1cb #15 0x104c580 at dofileread+0x70 #16 0x104c1d8 at sys_read+0x78 #17 0x154c7b9 at syscall+0x3e9 Uptime: 1d2h4m47s Fatal trap 12: page fault while in kernel mode cpuid =3D 0; apic id =3D 00 fault virtual address =3D 0x0 fault code =3D supervisor read, page not present instruction pointer =3D 0x20:0x0 stack pointer =3D 0x28:0x1df3a8d4 frame pointer =3D 0x28:0x1df3a90c code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, def32 1, gran 1 processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 932 (bacula-fd) trap number =3D 12 panic: page fault cpuid =3D 0 time =3D 1642636048 KDB: stack backtrace: #0 0x10327ae at kdb_backtrace+0x4e #1 0xfed128 at vpanic+0x118 #2 0xfed004 at panic+0x14 #3 0x154bfd5 at trap_fatal+0x335 #4 0x154c013 at trap_pfault+0x33 #5 0x154b71f at trap+0x36f #6 0xffc0319d at PTDpde+0x41a5 #7 0x12c33ce at ffs_read+0x31e #8 0x157b77d at VOP_READ_APV+0x5d #9 0x10b980a at vn_read+0x18a #10 0x10b95da at vn_io_fault_doio+0x3a #11 0x10b7232 at vn_io_fault1+0x162 #12 0x10b548b at vn_io_fault+0x1cb #13 0x104c580 at dofileread+0x70 #14 0x104c1d8 at sys_read+0x78 #15 0x154c7b9 at syscall+0x3e9 #16 0xffc033e7 at PTDpde+0x43ef Uptime: 23h37m42s Physical memory: 3026 MB --=20 You are receiving this mail because: You are the assignee for the bug.=
