Hello, Today I had another crash (It looks like is unrelated, since it happened at night, when I wasn't doing anything, but is really strange that is that is exactly same line, as in previous one). (this time I wrote "panic" right away in the debugger, as it was in manual) --- dmesg --- kernel trap 12 with interrupts disabled Fatal trap 12: page fault while in kernel mode fault virtual address = 0xd131cc64 fault code = supervisor read, page not present instruction pointer = 0x8:0xc04e9d3f stack pointer = 0x10:0xcbd25c24 frame pointer = 0x10:0xcbd25c44 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process = 27 (swi5: clock sio) panic: from debugger KDB: stack backtrace: Uptime: 10d12h46m53s Dumping 255 MB 16 32 48 64 80 96 112 128 144 160 176 192 208 224 240 Dump complete Automatic reboot in 15 seconds - press a key on the console to abort --- dmesg --- --- kgdb --- [chinatsu]:/usr/obj/usr/src/sys/CHINATSU# kgdb kernel.debug /var/crash/vmcore.1 [GDB will not be able to debug user-mode threads: /usr/lib/libthread_db.so: Undefined symbol "ps_pglobal_lookup"] GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
