Since that time, this machine has been randomly panicing such as: Fatal trap 12: page fault while in kernel mode mp_lock = 00000003; cpuid = 0; lapic.id = 00000000 fault virtual address = 0x36 fault code = supervisor write, page not present instruction pointer = 0x8:0xc01f60fe stack pointer = 0x10:0xf25cdab8 frame pointer = 0x10:0xf25cdb58 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 = 454 (perl) interrupt mask = net bio cam <- SMP: XXX trap number = 12 panic: page fault mp_lock = 00000003; cpuid = 0; lapic.id = 00000000 boot() called on cpu#0 >From my symbol table, this particular panic appears to have occured in vm_fault: c01f5fcc T vm_fault c01f6b1c T vm_fault_wire This appears to be pretty consistent (the instruction pointer). It used to panic both where I mentioned above and also in pmap.c. Since I did the last cvsup and kernel rebuild, I haven't seen one from the pmap area. Any ideas? - Forrest W.
