Description Nathan Carter 2005-10-21 09:40:18 UTC 
The system will not boot the kernel. When you boot it displays:
KDB: debugger backends: ddb
KDB: current backend: ddb

fatal kernel trap
execution = 0x4 (instruction storage interrupt)
virtual address = 0x3d66a0
srr0 = 0x3d66a0
srr1 = 0x8003032
currthread = 0x4bbc98
pid = 0, comm =
thread pid 0 tid 0
stopped at 0x3d66a0: isync
db>

Fix: 

This is fixed in r 1.99.2.1 of sys/powerpc/powerpc/pmap.c, which is
in the 6.0-RC1 snapshot.
Please try out the RC1 iso !
How-To-Repeat: Boot from the CD.
Hit enter to boot immediately when prompted

Old report: http://www.freebsd.org/cgi/query-pr.cgi?pr=87775
I know this was reported just yesterday.

Which is what I'm running

Machine is: G5 iMac
I get the same problem

Description
        The system will not boot the kernel. When you boot it displays:
        KDB: debugger backends: ddb
        KDB: current backend: ddb
        (in old report it has the fatal kernel trap...I don't get that message just the above)

How-To-Repeat
        Boot from the CD.
        Hit enter to boot immediately when prompted

Will reply with more information, Just ask what else you need me to do
and run.

Thanks, Happy to help FreeBSD :)

FreeBSD/PPC doesn't currently run on G5 CPUs. I guess I should put in 
some code that prints that out at boot-time until the support is there.
