I'm experiencing some severe keyboard stuttering on my laptop. The
problem is particularly bad in X, and I believe it also occurs at the
console, though I'm having a difficult time verifying that. The problem
shows up as repeated characters (not regular key-repeat-related), and
sometimes dropped key presses.

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.
dmesg and dmidecode outputs are available at:

This is a Dell Inspiron 9400.
The Dell Inspiron 9400 and Inspiron E1705 are pretty much the same
laptop. I'm glad to hear it's not just my keyboard or anything like that.
It sounds like there are several others who are experiencing the same or
related issues.
Is there a way to change the interrupt trigger for the keyboard (the
other devices seem to work just fine)? Is there a way to force i8042 to
XT-PIC on interrupt 1, to see whether it's related to the interrupt
trigger, or something else that just looks similar? Any other ideas for
debugging or fixing?
I'd really love not to have to do the noapic or nolapic workaround...
