This didn't occur until I compiled an SMP kernel. I'm running -current as of last Friday and the system has 512mb of memory and 4 drives on Adaptec controllers (1 - 4gig on one controller and 3 - 9gig on the other). Untarring a file will interestingly enough crash the system at around the same appoximate place in the tar image every time, although it's crashed while building ports also. The system drops to the debugger with the following: Fatal trap 12: page fault while in kernel mode mp_lock = 01000002; cpuid=1; lapic.id = 01000000(I've also seen it for cpuid0) fault virtual address = 0x0 fault code = supervisor write, page not present instruction pointer = 0x8:0xf0216357 stack pointer = 0x10:0xff618ce8 frame pointer = 0x10:0xff618d0c code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 243 (tar) interrupt mask = net tty bio cam <-SMP:XXX kernel: type 12 trap, code 0 Stopped at generic_bzero+0xf: repe stosl %es:(%edi) Any ideas as to what to look for ?
