X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 13 Oct 2005 21:12:24 -0000 Hello list! I have been successfully been running 5.3 for a couple of weeks when i decided i should upgrade to 5.4 stable. Now the make world went fine except mergemaster complaining it couldn't find usr/src/etc or something similar. I made make buildkernel wich also went fine. But when I booted into my upgraded system I got kernel panic, so I made another restart and this time it went ok. Yestoday I removed SCSI card and DAT tape and NIC so I can have them in my main server. Now i cant get past this: freebsd 5.4-stable kernel trap 12 with interupts disabled Fatal trap 12: page fault while in kernel mode fault virtual address = 0x9 fault code = supervisor write, page not present instruction pointer = 0x8 :0xc077c073 stack pointer = 0x10 :0xc0c20d00 frame pointer = 0x10 :0xc0c20d0c code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process = 0 () trap number = 12 panic: page fault Uptime: 1s So my attack-plan is to reinstall system from scratch and never do make buildworld & make buildkernel again, BUT, I have a whole lot of information remaining on both disks that are in right now. From what I could see in the installer, fbsd installer wont let me "install in a different directory with filesystem still intact" like windows does....or does it? UPDATE: I have now done what has been advised, to do boot kernel.old at the boot loader prompt, and I get the same error...running out of options here... :/ Please help! :) // Alex
