Troubles booting sparc64 SMP 2.4.18 kernel

Hi all,

I've got linux running on an dual CPU E220R. The base system is Debian Woody and 
I've installed the sparc64 compiler and binutils

    root@razor > sparc64-linux-gcc -v
    Reading specs from /usr/lib/gcc-lib/sparc-linux/3.0.3/specs
    Configured with: ../src/configure -v --enable-languages=c --prefix=/usr 
      --infodir=/share/info --mandir=/share/man --enable-shared --with-gnu-as 
      --with-gnu-ld --with-system-zlib --enable-long-long --enable-nls --without-x 
      --without-included-gettext --disable-checking --with-cpu=v7 sparc-linux
    Thread model: single
    gcc version 3.0.3
    root@razor > ld -V
    GNU ld version 2.11.92.0.12.3 20011121 Debian/GNU Linux
      Supported emulations:
       elf32_sparc
       sparclinux
       elf64_sparc
       sun4

I am able to build a working uni-processor sparc64 kernel which boots and works 
as expected :

    root@razor > cat sizeof.c 
    #include <stdio.h>
    
    int main (void)
    {	printf ("sizeof (void*) = %d\n", sizeof (void*)) ;
        return 0 ;
    } /* main */

    root@razor > sparc64-linux-gcc -m64 sizeof.c -o sizeof
    root@razor > ./sizeof 
    sizeof (void*) = 8

This seems to suggest that this is a 64 bit aware kernel.

If I then take the working uni-processor kernel tree, switch
on SMP support and then do 

    make dep ; make clean ; make ; make modules ; 
    make modules_install

and copy the kernel to /boot, run SILO and reboot, it starts off
OK but the seems to fail just after init is run. This is the last 
part of the boot messages:

    IP: routing cache hash table of 4096 buckets, 64Kbytes
    TCP: Hash tables configured (established 32768 bind 32768)
    NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
    VFS: Mounted root (ext2 filesystem) readonly.
    version 2.84 booting
    cannot ®¨Høcannot fork, retry..
    cannot fork, retry..
    cannot fork, retry..

I have also tried to boot a 32 bit only SMP kernel but that fails in the
same way. Anybody have any clues?

Cheers,
Erik
