My own Malta kernels are built from rather old 2.6 sources, so it's not

clear that all the same options are required/possible.  The questions that

come to mind for me are:

 

1) You're booting a big-endian kernel.  The Malta board can be set up

    for either endianness with a DIP switch, but I believe that it ships

    from the factory in little-endian mode.  Have you verified that the

    endianness setup?

After reset, I get the message saying that, board is in Big endian mode. So,  I assume that there is no problem here.

2)  You're configuring for hot-pluggable CPUs.  That isn't fully supported

     in the old source base I've got.  It may be fixed in 2.6.14, but do you

     actually need it on a Malta?

 

3) You've got support for MIPS MT (the multithreading extension) enabled,

    with the slave-virtual-processor boot loader, etc.  This stuff only works

    on a 34K core, and could cause severe problems if invoked on a 4Kc.

    At least you don't have SMP/SMTC multi-virtual-processor support

    enabled, which would *definitely* cause a prompt crash on a 4Kc,

    but please turn MIPS_MT off.  If MIPS MT + VPE loader are really

    selected options in the default malta config file, it needs to be fixed!

I reset the above options, but the same
problem persists. If I compiled 2.6.10 with default configuration
(endian is changed to big endian), the board comes up without any
problem.
