I have been up and running now for about a half hour - since I did not

The only non-standard thing I did was to use the nohpet directive at
boot time - I did NOT enter the previously used taskset command to alter
X's affinity.

I have been banging away on my keyboard for about a half hour now with
no problems. While this is not conclusive on a 'soft' problem, from what
I experienced yesterday I would have expected to have seen the problem
by now.

Please let me know if there are any other items you would like to do or
options you would like me to try.

Thanks. So this clearly indicates that you are hitting either hardware
bug, or some bug in our HPET handling code.

Adding Ingo and Thomas to CC. Short summary -- Chris (and apparently other
people) are sometimes seeing repeated keypressess when HPET timer is used.
This doesn't happen when alternative clocksource is used.

Now, it would be interesting to know what the detailed difference is,
when the system is booted with and without nohpet.

Chris, can you please provide the dmesg output and the output of
/proc/timer_list for each bootup ?

.config file would be interesting as well.

Thanks,
tglx
