me again,
found out myself that it always worked to mask
the local timer out.
cat /proc/interrupts was just the wrong way (tool)
to test if it is really masked out since it only shows the
external timer irqs.
top and xosview showed an idle time of 100% for cpu with masked
out local timer even if there were processes on it.
this means that the timer didn't update local kstat info anymore
and so mytry to just mask it worked.
a hint would have been helpful, though.
greets,
klaas
