Patched rc6 ex BK OK and compiled with gcc295-3 OK

On a P4/533-2.4Ghz/512MB with udma5 IDE ~50MB/s:

Shows severe interactivity problems and hangs

Scroll and mouse hangs and delayed response to keyboard 
greater 1s are easily observable.

Test script: tstinter V0.1

To reproduce cd to dir with script and execute from X console: 
  ./tstinter start

More instructions in script

Other kernel results: 
   2.4.18 PIO DIES - see msg w. script, 
   2.4.18 udma2 OK, 
   2.4.19 Bad, 
   2.4.20 Bad, 
   2.4.21-rc1 Bad,
