Given that that is a single bit set, it could possibly be due to bad RAM. Does your kernel have debug symbols? If so, running 'l *0xffffffff80186249' (from the 'instruction pointer' line in the fault message) would be helpful. > fault code = supervisor write data, page not present > instruction pointer = 0x8:0xffffffff80186249 > stack pointer = 0x10:0xffffffff8065f200 > frame pointer = 0x10:0x36ee7f > code segment = base 0x0, limit 0xfffff, type 0x1b > = DPL 0, pres 1, long 1, def32 0, gran 1 > processor eflags = resume, IOPL = 0 > current process = 26 (irq256: bge0) > trap number = 12 > p[*CURSOR STOPPED HERE*] -- John Baldwin _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
