sparc32 netboot failure report

["Aaron D. Johnson" <adj@fnord.fort-collins.co.us>]

Kernel image was
http://people.debian.org/~jbailey/d-i/sparc/daily/sparc32/netboot/boot.img
dated 2004-03-14.  md5sum is 996b709a5a6dfcbb8ed4c39ad94bc2c1.

Hardware is a SparcSTATION IPC (4/40, I think), 36 Mbytes RAM, 1Gbyte
SCSI disk, floppy drive.

The screen reads:

  ok boot net
  Booting from: le(0,0,0)
  3b0800 bootmem_init: Scan sp_banks,  init_bootmem(spfn[27a],bpfn[3b1],mlpfn[2400
  ])
  
  Watchdog reset
  Trap # (hex) 24

The "bootmem_init" message seems to be normal if the kernel is
compiled with DEBUG_BOOTMEM #defined.

Trap 0x24 looks to be SP_TRAP_CPDIS/Co-Processor disabled, which
doesn't really make any sense to me.

I'll happily try new kernel images and different kernel command line
arguments, but I don't have the resources to build my own kernels
right now (this being the only SPARC box in the house).  I'll set up a
cross compilation environment if someone points me at instructions,
though.
