OK. I must be doning something stupid. I can't break into the debugger on my laptop (Libretto 50CT 32M memory, no port replicators installed). I tried the usual Ctl-Alt-Escape, but no joy. Has anybody else run into this? This is with -current as of late last week. Warner P.S. Here's my config file. It is nearly the same as the standard PCCARD with options DDB added. # # PCCARD -- GENERIC laptop support # # 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 # <URL:http://www.FreeBSD.ORG/>; # # 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: PCCARD,v 1.2 1997/11/11 00:47:01 nate Exp $ machine "i386" cpu "I386_CPU" cpu "I486_CPU" cpu "I586_CPU" cpu "I686_CPU" ident PCCARD 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 config kernel root on wd0 controller isa0 controller pci0 controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 vector fdintr disk fd0 at fdc0 drive 0 options "CMD640" # work around CMD640 chip deficiency controller wdc0 at isa? port "IO_WD1" bio irq 14 vector wdintr disk wd0 at wdc0 drive 0 controller wdc1 at isa? port "IO_WD2" bio irq 15 vector wdintr options ATAPI #Enable ATAPI support for IDE bus options ATAPI_STATIC #Don't do it as an LKM device wcd0 #IDE CD-ROM controller aic0 at isa? port 0x340 bio irq 11 vector aicintr 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 device npx0 at isa? port "IO_NPX" irq 13 vector npxintr # # Laptop support (see LINT for more options) # device apm0 at isa? flags 0x32 # Advanced Power Management # PCCARD (PCMCIA) support controller card0 device pcic0 at card? device pcic1 at card? device sio0 at isa? port "IO_COM1" flags 0x10 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 psm0 at isa? port "IO_KBD" conflicts tty irq 12 vector psmintr options PSM_HOOKAPM #hook the APM resume event options PSM_RESETAFTERSUSPEND #reset the device at the resume event options DDB device ed0 at isa? port 0x280 net irq 10 iomem 0xd8000 vector edintr device ep0 at isa? port 0x300 net irq 10 vector epintr device fe0 at isa? port 0x300 net irq ? vector feintr pseudo-device loop pseudo-device ether pseudo-device sl 1 # iijppp uses tun instead of ppp device #pseudo-device ppp 1 pseudo-device tun 1 pseudo-device pty 16 pseudo-device gzip # Exec gzipped a.out's # KTRACE enables the system-call tracing facility ktrace(2). # This adds 4 KB bloat to your kernel, and slightly increases # the costs of each syscall. options KTRACE #kernel tracing # This provides support for System V shared memory. # options SYSVSHM To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
