Date: Fri, 12 Jan 2001 18:46:45 -0800 Message-ID: <18670.979354005@winston.osd.bsdi.com> From: Jordan Hubbard Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I've actually been seeing this for about 2 months now but only just now got motivated enough to enable crashdumps and get some information on what happens whenver I try to use the printer attached to my (sadly :) -current SMP box: IdlePTD 3682304 initial pcb at 2e70e0 panicstr: page fault panic messages: --- Fatal trap 12: page fault while in kernel mode cpuid = 0; lapic.id = 00000000 fault virtual address = 0xffff8640 fault code = supervisor write, page not present instruction pointer = 0x8:0xc8dc8676 stack pointer = 0x10:0xc8280f88 frame pointer = 0x10:0xc8280f9c 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 = 12322 (irq7: lpt0) trap number = 12 panic: page fault cpuid = 0; lapic.id = 00000000 boot() called on cpu#0 If anybody wants a fuller traceback then I'll compile up a kernel with debugging symbols, but it's going to be pretty sparse anyway since it basically only shows the trap() from the page fault and the subsequent panic. - Jordan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
