Re: help with inittab

I've tried what you've mentioned below, i.e removing the /sbin/init and
just having the /bin/sh in the init/main.c file and I don't get a
standalone shell. I am having a Linux 2.4 Kernel (Montavista 3.1)
running on a PPC405 in a Xilinx Virtex4 FX100 FPGA.

You mentioned it could be a hardware problem. Are there any errata which
could explain the h/w bug?=20


Thanks,
Chetan Anantharaman

    For debugging or single user purposes you do not need to run init or
have an inittab.
    There have been several sugestions that there may be a hardware
problem - there are a number that are possible.

    I was stalled here for some time because my UartDriver was
accidentally using the physical IO address instead of the virtual one
    and I had created a temporary phys=3Dvirtual entry in the tbl that =
was
conveniently getting blow away just here.

    You can try to isolate your problem by changing your boot ramdisk
(inramfs or initrd)

    Eliminate or rename /init /sbin/init /linuxrc and any of the other
permutations that linux tries to execute in init/main.c they are all
listed very near where you stopped.
    make sure you have /bin/sh

    reboot on that ramdisk  if you have an "init" related problem then
you should get a standalone shell.
    If you have a hardware problem you will likely still stop at the
same place.
