 Just a shot in the blue:
 I have a similar Dell machine, where we fail to fire up the second cpu.
 I think there was a warning message in the dmesg (later) somewhere, but
 if you don't look closely it scrolls by way too fast.
 
 I never fully analyzed the failure, but somehow the secondary cpu crashed
 early, before making it into the idle loop. Additionally it could be 
 considered a bug that this state confuses our internal state so much that
 the kernel is completely useless.
 
 Can you try to boot the i386 cd, interrupt the cd bootloaders timer and
 do:
 
    boot -1
 
 to boot with only one cpu attached?
 
 Thanks,
 
 Martin
