I am running FreeBSD 6-STABLE (last update 14.5.06) on a Fujitsu Siemens Amilo A notebook. This machine has internet access via kppp and a Creative ModemBlaster V.92 serial modem. Sometimes when surfing on the internet (most times with Opera 8.51 AFAIR) the system completly locks up and reboots. I found http://www.at.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html and tried to analysis the crash dump in /var/crash but I am totally new to these things. "kgdb kernel.debug /var/crash/vmcore.2" on my system gives the following output: [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] (...) Unread portion of the kernel message buffer: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x29 fault code = supervisor write, page not present instruction pointer = 0x20:0xc06ad6a6 stack pointer = 0x28:0xd992f9d0 frame pointer = 0x28:0xd992fa00 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 793 (opera) trap number = 12 panic: page fault Uptime: 19m31s Dumping 478 MB (2 chunks) chunk 0: 1MB (159 pages) ... ok chunk 1: 478MB (122352 pages) 462 446 430 414 398 382 366 350 334 318 302 286 270 254 238 222 206 190 174 158 142 126 110 94 (CTRL-C to abort) (CTRL-C to abort) 78 (CTRL-C to abort) (CTRL-C to abort) (CTRL-C to abort) 62 46 30 14 #0 doadump () at pcpu.h:165 165 __asm __volatile("movl %%fs:0,%0" : "=r" (td)); (kgdb) quit Has anybody an idea what goes wrong on my system? What could I do in order to find out what goes wrong? Many thanks in advance, Michael
