the problem is in kern/kern_switch.c

Theoretically the message "corrected slot count (0->1)" indicates that 
the erro was avoided,
however there may be a threaded program that still has the problem (the 
avoiding code only happens on
non-threaded programs where it is possible to know what the value should 
be (1).

interesting to see the reults of 'ps' . But you may need a serial 
debugger to capture this..
iIt is unfortunatly possible htat this is too early to  get into teh 
debugger, however i am working on this problem today.
