Fatal trap 12: page fault while in kernel mode fault virtual address = 0x58 fault code = supervisor read page not present instruction pointer = 0x8:0xc0212cab stack pointer = 0x10:0xc0306f84 frame pointer = 0x10:0xc0306f88 code segment = base 0x0, limit oxfffff, type 0x16 = DPL0, press 1 def32 1 gran 1 processor eflags = interrupt enabled, resume, IOPL=0 current process = 0 () interrupt mask = trap number = 12 panic: page fault Automatic reboot in 15 seconds at the begining i belived i was produced because the 3com card was not available, but i also tried to run the new kernel in anoter pc and the behavior is the same. My pc has an intel pentium III, 500Mhz processor, 64 Mb ram. the configuration for my new kernel is the following ############################################################# # My custom kernel config file # machine "i386" cpu "I586_CPU" ident CASA maxusers 15 ## check what the hell is maxdsiz options "MAXDSIZ=(256*1024*1024)" options "DFLDSIZ=(256*1024*1024)" options GPL_MATH_EMULATE #Support for x87 emulation options INET #InterNETworking options FFS #Berkeley Fast Filesystem options FFS_ROOT #FFS usable as root device [keep this!] options MFS #Memory Filesystem options MFS_ROOT #MFS usable as root device, "MFS" req'ed options NFS #Network Filesystem options "CD9660" #ISO 9660 Filesystem options PROCFS #Process filesystem options "COMPAT_43" #Compatible with BSD 4.3 [KEEP THIS!] options SCSI_DELAY=15000 #Be pessimistic about Joe SCSI device options UCONSOLE #Allow users to grab the console options FAILSAFE #Be conservative options USERCONFIG #boot -c editor options INTRO_USERCONFIG options VISUAL_USERCONFIG #visual boot -c editor options PQ_LARGECACHE options USER_LDT options "VM86" options COMPILING_LINT config kernel root on wd0 controller isa0 controller pnp0 controller eisa0 controller pci0 controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 disk fd0 at fdc0 drive 0 disk fd1 at fdc0 drive 1 options "CMD640" # work around CMD640 chip deficiency controller wdc0 at isa? port "IO_WD1" bio irq 14 disk wd0 at wdc0 drive 0 disk wd1 at wdc0 drive 1 controller wdc1 at isa? port "IO_WD2" bio irq 15 disk wd2 at wdc1 drive 0 disk wd3 at wdc1 drive 1 options ATAPI #Enable ATAPI support for IDE bus options ATAPI_STATIC #Don't do it as an LKM device acd0 #IDE CD-ROM device wfd0 #IDE Floppy (e.g. LS-120) # A single entry for any of these controllers (ncr, ahb, ahc) is # sufficient for any number of installed devices. controller ncr0 controller ahb0 controller ahc0 controller isp0 controller dpt0 # DPT options options DPT_RESTRICTED_FREELIST options DPT_FREELIST_IS_STACK options DPT_TIMEOUT_FACTOR=4 options DPT_INTR_DELAY=200 # Some motherboards need that options DPT_LOST_IRQ options DPT_RESET_HBA ############### controller adv0 at isa? port ? cam irq ? controller adw0 controller bt0 at isa? port ? cam irq ? controller aha0 at isa? port ? cam irq ? controller scbus0 device da0 #device sa0 device pass0 device cd0 #Only need one of these, the code dynamically grows device wt0 at isa? port 0x300 bio irq 5 drq 1 device mcd0 at isa? port 0x300 bio irq 10 controller matcd0 at isa? port 0x230 bio device scd0 at isa? port 0x230 bio # atkbdc0 controlls both the keyboard and the PS/2 mouse controller atkbdc0 at isa? port IO_KBD tty device atkbd0 at isa? tty irq 1 device psm0 at isa? tty irq 12 device vga0 at isa? port ? conflicts # splash screen/screen saver pseudo-device splash # syscons is the default console driver, resembling an SCO console device sc0 at isa? tty # Enable this and PCVT_FREEBSD for pcvt vt220 compatible console driver device vt0 at isa? tty options XSERVER # support for X server #options FAT_CURSOR # start with block cursor # If you have a ThinkPAD, uncomment this along with the rest of the PCVT lines #options PCVT_SCANSET=2 # IBM keyboards are non-std device npx0 at isa? port IO_NPX irq 13 device apm0 at isa? disable flags 0x31 # Advanced Power Management device sio0 at isa? port "IO_COM1" flags 0x10 tty irq 4 device sio1 at isa? port "IO_COM2" tty irq 3 device sio2 at isa? disable port "IO_COM3" tty irq 5 device sio3 at isa? disable port "IO_COM4" tty irq 9 # Parallel port device ppc0 at isa? port? flags 0x40 net irq 7 controller ppbus0 device lpt0 at ppbus? device plip0 at ppbus? device ppi0 at ppbus? controller vpo0 at ppbus? controller vp0 at ppbus? # # revision 1.20 of this file. device ed0 at isa? port 0x280 net irq 10 iomem 0xd8000 device ie0 at isa? port 0x300 net irq 10 iomem 0xd0000` device ep0 at isa? port 0x300 net irq 10 device ex0 at isa? port? net irq? device fe0 at isa? port 0x300 net irq ? device le0 at isa? port 0x300 net irq 5 iomem 0xd0000 device lnc0 at isa? port 0x280 net irq 10 drq 0 device ze0 at isa? port 0x300 net irq 10 iomem 0xd8000 device zp0 at isa? port 0x300 net irq 10 iomem 0xd8000 device cs0 at isa? port 0x300 net irq ? pseudo-device loop pseudo-device ether pseudo-device sl 1 pseudo-device ppp 1 pseudo-device tun 1 pseudo-device pty 100 pseudo-device gzip # Exec gzipped a.out's pseudo-device snp 5 pseudo-device log options MAXCONS=12 options SYSVSHM options SYSVMSG options SYSVSEM pseudo-device bpfilter 4 #Berkeley packet filter ######################################################## any comment will be welcome.
