Clark" , current@FreeBSD.ORG Subject: Re: Kernel Panic from Yesterday's CVSup References: Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I have seen both a trap 12 and a trap 9 from a Friday Feb. 2 kernel. This is occuring on my laptop (AST Ascentia 810N) which I can't seem to get to create a core dump. Here is a hand transcription of what I see. Mounting root from ufs:/dev/ad0s1a pccard: card inserted, slot 0 pccard: card inserted, slot 1 kernel trap 9 with interrupts disabled Fatal trap 9: general protection fault while in kernel mode instruction pointer = 0x8:0xc0270ad8 stack pointer = 0x10:0xc2fb4f50 frame pointer = 0x10:0xc2fb4f64 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process = 16 (irq14:ata0) kernel: type 9 trap, code=0 Stopped at sw1b+0x77: ltr %si backtrace sw1b(4000) at sw1b+0x77 (note this is actually swtch()) ithd_loop(0,c2fb4fa8) at ithd_loop+0xf7 fork_exit(c0275bd0,0,c2fb4fa8_ at fork_exit+0x2d fork_trampoline() at fork_trampoline+0x8 I don't have WITNESS or INVARIANTS at this time and don;t have a serial console so I can't capture the output. I can try adding these to my kernel and transcribe a little bit by hand. I can also send my kernel config and dmesg from a Nov kernel which boots.
