Same problem here. Intel Core 2 Duo with 2.6.19-rc1 x86_64 SMP. Happens on
2.6.17 too. I use 'noapic' as a workaround but that disables one of the CPU
core of course.
I cannot reproduce the problem within the console nor gdm. Only on the X
desktop.
John,
It looks like the only clocksource available on David's box is
"jiffies" although the processor shows that it supporst tsc and PM
timer is enabled and I think that this is what causes keyboard
stuttering in X. See http://bugzilla.kernel.org/show_bug.cgi?id=7291.
I believe clocksources is your turf, could you please take a look at
this.
Thanks!
