Hi, Is this still reproducible? Cheers, Antonio Huete ---------------------------------------- Bug #1791: Panic: "Fatal trap 12: page fault while in kernel mode" http://bugs.dragonflybsd.org/issues/1791#change-12534 * Author: ftigeot * Status: Feedback * Priority: Normal * Assignee: * Category: Kernel * Target version: 4.2.x ---------------------------------------- I have just been bitten by this panic on a 4 cores Xeon server running DragonFly 2.6.3/i386. It is usually lightly loaded and mainly used for mail services. I have also setup a local chroot with a devfs mount of /dev and a nullfs mount of /usr/pkgsrc/distfiles to build packages. The panic occurred just after I exited a chrooted root shell. I wasn't able to get a core dump: the keyboard was completely unresponsive in the debugger and I had to reboot the machine with the reset switch. Details of the crash follow: Fatal trap 12: page fault while in kernel mode mp_lock = 00000002; cpuid = 2; lapic.id = 04000000 fault virtual address = 0 fault code = supervisor read, page not present instruction pointer = 0x8:0xc02d0a55 stack pointer = 0x10:0xe30729ac frame pointer = 0x10:0xe3072a40 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 = 89056 (zsh) current thread = pri 6 <- SMP: XXX kernel: type 12 trap, code=0 CPU2 stopping CPUs: 0x0000000b stopped Stopped at devfs_getattr+0x1b: movl 0(%edi),%edx db> -- You have received this notification because you have either subscribed to it, or are involved in it.
