HELP, I cannot get a kernel to boot. I have modified the GENERIC configuration file to suit my system (see below). The kernel compiles fine, but when I try to boot the new kernel I get a panic. The following is the output from the boot process from the GENERIC kernel. ahc0: Probing channel A ahc0 waiting for scsi devices to settle ahc0: target 0 synchronous at 10.0MB/s, offset = 0xf (ahc0:0:0): "CONNER CFP2105S 2.14GB 2B4B" type 0 fixed SCSI 2 sd0(ahc0:0:0): Direct-Access 2048MB (4194304 512 byte sectors) ahc0: target 1 synchronous at 4.0MB/s, offset = 0xf (ahc0:1:0): "TOSHIBA CD-ROM XM-3601TA 0725" type 5 removable SCSI 2 cd0(ahc0:1:0): CD-ROM cd0(ahc0:1:0): NOT READY asc:3a,0 Medium not present can't get the size vga0 <Display device> rev 0 on pci0:15 pci0: uses 8392704 bytes of memory from ff000000 upto fffbffff. pci0: uses 256 bytes of I/O space from fc00 upto fcff. changing root device to sd0a When I boot the other kernel I get the following message in place of the 'changing root device to sd0a': 'panic: Nobody want to mount mount my root for me' 'hit reset please' Can anybody give me some hints Greg Shaffer # # GENERIC -- Generic machine with WD/AHx/NCR/BTx family disks # # $Id: GENERIC,v 1.46 1995/06/11 19:31:11 rgrimes Exp $ # machine "i386" #cpu "I386_CPU" #cpu "I486_CPU" cpu "I586_CPU" ident PICKLES maxusers 10 #options MATH_EMULATE #Support for x87 emulation options INET #InterNETworking #options FFS #Berkeley Fast Filesystem options NFS #Network Filesystem options MSDOSFS #MSDOS Filesystem options "CD9660" #ISO 9660 Filesystem options PROCFS #Process filesystem options "COMPAT_43" #Compatible with BSD 4.3 options "SCSI_DELAY=15" #Be pessimistic about Joe SCSI device options BOUNCE_BUFFERS #include support for DMA bounce buffers options UCONSOLE #Allow users to grab the console config kernel root on sd0 controller isa0 controller pci0 controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 vector fdintr disk fd0 at fdc0 drive 0 #disk fd1 at fdc0 drive 1 #tape ft0 at fdc0 drive 2 #controller wdc0 at isa? port "IO_WD1" bio irq 14 vector wdintr #disk wd0 at wdc0 drive 0 #disk wd1 at wdc0 drive 1 #controller wdc1 at isa? port "IO_WD2" bio irq 15 vector wdintr #disk wd2 at wdc1 drive 0 #disk wd3 at wdc1 drive 1 #controller ncr0 #controller ahc0 controller ahc0 at isa? bio irq ? vector ahcintr # port??? iomem? #controller bt0 at isa? port "IO_BT0" bio irq ? vector btintr #controller uha0 at isa? port "IO_UHA0" bio irq ? drq 5 vector uhaintr #controller ahc1 at isa? bio irq ? vector ahcintr #controller ahb0 at isa? bio irq ? vector ahbintr #controller aha0 at isa? port "IO_AHA0" bio irq ? drq 5 vector ahaintr #controller aic0 at isa? port 0x340 bio irq 11 vector aicintr #controller nca0 at isa? port 0x1f88 bio irq 10 vector ncaintr #controller nca1 at isa? port 0x350 bio irq 5 vector ncaintr #controller sea0 at isa? bio irq 5 iomem 0xc8000 iosiz 0x2000 vector seaintr controller scbus0 at ahc0 # Single bus device disk sd0 at scbus0 target 0 # tape st1 at scbus0 target 6 device cd0 at scbus0 target 1 #controller scbus0 #device sd0 #device st0 #device cd0 #Only need one of these, the code dynamically grows #device wt0 at isa? port 0x300 bio irq 5 drq 1 vector wtintr #device mcd0 at isa? port 0x300 bio irq 10 vector mcdintr #device mcd1 at isa? port 0x340 bio irq 11 vector mcdintr #controller matcd0 at isa? port ? bio #device scd0 at isa? port 0x230 bio # syscons is the default console driver, resembling an SCO console device sc0 at isa? port "IO_KBD" tty irq 1 vector scintr # Enable this and PCVT_FREEBSD for pcvt vt220 compatible console driver #device vt0 at isa? port "IO_KBD" tty irq 1 vector pcrint #options "PCVT_FREEBSD=210" # pcvt running on FreeBSD 2.1 #options XSERVER # include code for XFree86 device npx0 at isa? port "IO_NPX" irq 13 vector npxintr device sio0 at isa? port "IO_COM1" tty irq 4 vector siointr device sio1 at isa? port "IO_COM2" tty irq 3 vector siointr #device sio2 at isa? port "IO_COM3" tty irq 5 vector siointr #device sio3 at isa? port "IO_COM4" tty irq 9 vector siointr #device lpt0 at isa? port? tty irq 7 vector lptintr #device lpt1 at isa? port? tty #device lpt2 at isa? port? tty # Order is important here due to intrusive probes, do *not* alphabetize # this list of network interfaces until the probes have been fixed. # Right now it appears that the ie0 must be probed before ep0.
