My problem appeared to be with the kernel config file that I was using. I hacked a new one from GENERIC and got a lot further. Now I get through the device probes and I can hear the machine start booting into multiuser mode but I can't see anything. Nothing is printed after the last device probe. The machine hangs later on when it is trying to start mpd. If I break into DDB, all the boot messages appear in a lump; sounds like some kind of wierd interrupt problem to me. Kernel config is: # # GENERIC -- Generic machine with WD/AHx/NCR/BTx family disks # # For more information read the handbook part System Administration -> # Configuring the FreeBSD Kernel -> The Configuration File. # The handbook is available in /usr/share/doc/handbook or online as # latest version from the FreeBSD World Wide Web server # # # An exhaustive list of options and more detailed explanations of the # device lines is present in the ./LINT configuration file. If you are # in doubt as to the purpose or necessity of a line, check first in LINT. # # $Id: GENERIC,v 1.90 1997/04/14 00:35:20 gibbs Exp $ machine "i386" cpu "I386_CPU" cpu "I486_CPU" cpu "I586_CPU" cpu "I686_CPU" ident GENERIC 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 [KEEP THIS!] 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 options FAILSAFE #Be conservative options USERCONFIG #boot -c editor options VISUAL_USERCONFIG #visual boot -c editor options DDB options UKKEYMAP options SYSVSHM options SYSVSEM options SYSVMSG options AHC_TAGENABLE options KTRACE options "CONSPEED=(115200)" # SMP kernel config file options: options SMP # Symmetric MultiProcessor Kernel options APIC_IO # Symmetric (APIC) I/O options NCPU=2 # number of CPUs options NBUS=2 # number of busses options NAPIC=1 # number of IO APICs options NINTR=24 # number of INTs options SMP_INVLTLB # #options SMP_PRIVPAGES # BROKEN, DO NOT use! #options SMP_AUTOSTART # BROKEN, DO NOT use! #options SERIAL_DEBUG # com port debug output options IPFIREWALL #firewall options IPFIREWALL_VERBOSE #print information about # dropped packets options "IPFIREWALL_VERBOSE_LIMIT=100" #limit verbosity options IPDIVERT #divert sockets config kernel root on wd0 controller isa0 controller eisa0 controller pci0 controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 vector fdintr disk fd0 at fdc0 drive 0 # A single entry for any of these controllers (ncr, ahb, ahc, amd) is # sufficient for any number of installed devices. controller ahc0 controller scbus0 device sd0 device od0 #See LINT for possible `od' options. device st0 device cd0 #Only need one of these, the code dynamically grows # 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 >= 2.0.5 #options XSERVER # include code for XFree86 #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 vector npxintr # # Laptop support (see LINT for more options) # device apm0 at isa? disable flags 0x31 # Advanced Power Management 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? disable port "IO_COM3" tty irq 5 vector siointr device sio3 at isa? disable 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 mse0 at isa? port 0x23c tty irq 5 vector mseintr device psm0 at isa? port "IO_KBD" conflicts tty irq 12 vector psmintr # 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.
