GENERIC kernel works, custom does not. I have tried using a config file that doesn't wire down the disks, and one that does with the same results. I included dmesg output and also my kernel config file. error: ... npx0: INT 16 interface changing root device to da0s1a changing root device to da0a error 6: panic: cannot mount root (2) dmesg output: avail memory = 17215488 (16812K bytes) Preloaded elf kernel "kernel.GENERIC" at 0xc0358000. ahc0: <Adaptec 284X SCSI host adapter> at 0x1c00-0x1cff irq 11 on eisa0 slot 1 ahc0: aic7770 >= Rev E, Single Channel A, SCSI Id=7, 4/255 SCBs Probing for PnP devices: Probing for devices on the ISA bus: sc0 on isa sc0: VGA color <16 virtual consoles, flags=0x0> ed0 at 0x300-0x31f irq 10 maddr 0xd0000 msize 16384 on isa ed0: address 00:00:79:84:41:3d, type WD8013EBT (16 bit) atkbdc0 at 0x60-0x6f on motherboard atkbd0 irq 1 on isa sio0 at 0x3f8-0x3ff irq 4 flags 0x10 on isa sio0: type 16450 sio1 at 0x2f8-0x2ff irq 3 on isa sio1: type 16450 fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa fd0: 1.44MB 3.5in vga0 at 0x3b0-0x3df maddr 0xa0000 msize 131072 on isa npx0 on motherboard npx0: INT 16 interface Waiting 15 seconds for SCSI devices to settle da0 at ahc0 bus 0 target 0 lun 0 da0: <COMPAQ 2105 15E6> Fixed Direct Access SCSI-2 device da0: 10.000MB/s transfers (10.000MHz, offset 15), Tagged Queueing Enabled da0: 532MB (1090999 512 byte sectors: 64H 32S/T 532C) da1 at ahc0 bus 0 target 1 lun 0 da1: <CONNER CP30200 SUN0207 4544> Fixed Direct Access SCSI-2 device da1: 5.000MB/s transfers (5.000MHz, offset 15) da1: 203MB (416108 512 byte sectors: 64H 32S/T 203C) changing root device to da0s1a kernel config: machine "i386" cpu "I486_CPU" ident ACME maxusers 32 options INET #InterNETworking options FFS #Berkeley Fast Filesystem options FFS_ROOT #FFS usable as root device options "CD9660" #ISO 9660 Filesystem options PROCFS #Process filesystem options "COMPAT_43" #Compatible with BSD 4.3 options UCONSOLE #Allow users to grab the console options FAILSAFE #Be conservative options USERCONFIG #boot -c editor options VISUAL_USERCONFIG #visual boot -c editor config kernel root on da0 controller isa0 controller pci0 controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 disk fd0 at fdc0 drive 0 controller ahc0 controller scbus0 at ahc0 device da0 disk da0 at scbus0 target 0 unit 0 disk da1 at scbus0 target 1 unit 0 device sa0 device pass0 device cd0 # 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 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 device npx0 at isa? port IO_NPX irq 13 device ed0 at isa? port 0x300 net irq 10 iomem 0xd0000 device ed1 at isa? port 0x340 net irq 12 iomem 0xcc000 pseudo-device loop pseudo-device ether pseudo-device pty 16 pseudo-device gzip # Exec gzipped a.out's options SYSVSHM options SYSVMSG options SYSVSEM pseudo-device bpfilter 4 #Berkeley packet filter >How-To-Repeat: build a custom kernel >Fix: use kernel.GENERIC >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
