I have been trying to get a custom PPC860 board up using MonteVista's Hard
Hat
2.0 distribution using a vxWorks bootrom.  I have made alot of progress in
the last
few days but have got stuck at the point here init is executed.  The IMMR is
set
to 0x02200000.  I ran across some old posts on the list referring to this
being set
too low for linux.  Could this be the problem?  If not does anyone have any
suggestions on what could be wrong?  Attached is the boot up output from the
console.

Thanks,
Mike O'Brien

Hello everyone,

    I have similar problems on my MPC8240 board with kernel 2.4.6.
After kernel mount the rootfs on the disk and execve("/sbin/init"),
the console shows as follows:
    Freeing unused kernel memory: 180k init
    INIT: version 2.77 booting
    Kernel panic: Attempted to kill init!
    Reboot in 180 seconds...
When I reboot the system and kernel runs to execve init, there is
nothing shown on the console after the "Freeing..." message. It seems
that the init program has been modified in the previous booting. And,
at this moment the console is still capable of echo any keys I pressed.
    I replace the init program with my testing progarm (staticly-linked
with libs); I found when I do fork(), the program hangs without
any messages. I added checkpoints in the kernel and found that kernel
completed sys_fork() without errors.
    My rootfs on the disk can be mounted and be kicked-off well with
kernel 2.2.17 on our board. The library is libc-2.1.3.so and ld-2.1.3.so.
My GCC is 2.95.2. The kernel booting messages are attached also.
    Does it have anything to do with memory management setup ? Please
advise me to deal with this. Any comments are welcome. Thank you.

Regards,
Paul Chu
