Pesa" To: "'hackers@FreeBSD.ORG'" Subject: panic: general protection fault Date: Sat, 14 Feb 1998 13:24:43 -0500 MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 8bit X-MIME-Autoconverted: from quoted-printable to 8bit by hub.freebsd.org id OAA00266 Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hello, I have been encountering the following panic for several months. I have been running this particular machine since June '97 on 2.2.2-Release. I initially got a similar Fatal trap 12 during the install, the workaround was to disable cpu caching in the bios during the install, then go back afterwards and re-enable. For the last several months I have become more dedicated to configuring this machine as my time frees up. I have changed out the memory in hopes it was a corrupt Simm, no luck. The Mo. Board is an Octek Hippo with an Intel Overdrive Cpu, it originally had an Intel 486 dx 4 /100. I seemed to get the same panic with either CPU. It has a Promise IDE controller with 2 ide drives, 1.6G and 540 MB seagate. It also has a 3Com 3C509 III ethernet card, I do remember seeing that the ep0 interface was buggy? I beleive that was on www.freebsd.com. I do not have another ethernet card swap at the moment. Following what is logged after the core dump: developer kernel log messages: > ess = Idle > interrupt mask = > panic: general protection fault > > syncing disks... > > Fatal trap 12: page fault while in kernel mode > fault virtual address = 0x10 > instruction pointer = 0x8:0xf012e2e6 > stack pointer = 0x10:0xf01d5ea4 > frame pointer = 0x10:0xf01d5eb4 > syncing disks... > > Fatal trap 12: page fault while in kernel mode > fault virtual address = 0x10 > fault code = supervisor read, page not present > instruction pointer = 0x8:0xf012e2e6 > stack pointer = 0x10:0xf01d5e70 > frame pointer = 0x10:0xf01d5e80 > 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 = Idle > interrupt mask = > panic: page fault > Fatal trap 9: general protection fault while in kernel mode > instruction pointer = 0x8:0xf01afe35 > stack pointer = 0x10:0xf01d6000 > frame pointer = 0x10:0x0 > panic: general protection fault > stack pointer = 0x10:0xf01d5ea4 > frame pointer = 0x10:0xf01d5eb4 > syncing disks... done I do not have much expereince with system programming in Unix so any help will be greatly appreciated, even a pointer in the right direction as to debug methods or documentation.
