But, it turns out to be moot. The kernel hangs when HZ is 1000
and resets immediately when HZ is 250 or 300. It could be that
the system tick timer isn't configurable and is hard-wired to
generate a 100Hz interrupt.
IMHO: if we are to fix any bugs in the system timer functions, we should
consider to enable the "tickless timer". With same the overhead should
be reduced drastically. Of course we need a programmable timer
"hardware" for this, but same might be in place anyway (Altera timer)
or could quite easily be done using VHDL.
