No dump device defined. Automatic reboot in 15 seconds - press a key on the console to abort If I just disable the second IDE channel, the system boots fine. FreeBSD=20 5.5/i386, which is also installed on this computer, boots fine with or=20 without that disk. I've been trying to get into the kernel debugger to get a backtrace, but=20 without luck. I've hooked up a serial console, but I just can't get into DD= B.=20 I've tried various option (adding debug.debugger_on_panic=3D"1"=20 to /boot/loader.conf, the BREAK_TO_DEBUGGER and KDB_UNATTENDED kernel optio= ns=20 as well as specifying "boot -d" at the boot loader - without any effect.=20 Since the panic happens before init is started, my dump device configuratio= n=20 in /etc/rc.conf isn't read either. How can I get meaningful debugging data out of this system? Oh, btw, notice the weird device name string for acd0. It's supposed to say= =20 <Pioneer DVD-ROM ATAPIModel DVD-106S 0122/E1.22>, and in the BIOS as well a= s=20 under FreeBSD 5.5/i386 it does. The erroneous strings shows up on FreeBSD 6= =2E1=20 with or without the second IDE channel being enabled. Any idea what might cause this? The full boot log follows bellow.
