[Bug 39315] Re: Keyboard random repeat and dropped key presses

[Christian Schuerer]

Unfortunately, there is no BIOS update for my notebook (Dell D620). I've
checked the DSDT, which didn't show any errors, so this shouldn't be
causing problems.

As I wrote in my report to bug# 64325, I can work normally only with
kernel 2.6.15 (the one from dapper).

I've even compiled kernel 2.6.18 and 2.6.19rc2-mm2 myself (optimised for
Intel Core 2 Duo) - but the problems described in both bug reports
aren't solved with any of them.

Additionally, I have disabled the boot splash screen (it causes a lot of
problems regarding the keyboard issue) and I'm using the kernel option
pci=assign-busses.

I can't estimate whether this is an kernel- or an application-based (X
or KDE) bug. Neither do I know what has changed from the kernel side
from 2.6.15 to 2.6.17, so that this all happens. I have to point out,
that problems regarding the keyboard only appear within X - but never on
the VT.

To sum up:

2.6.19rc-mm2, 2.6.18 and 2.6.17 only work if I use "noapic" and/or
"acpi=noirq", but with any of these options activated I've only ONE
core, which is not what I desire.

2.6.15 (from dapper) works (having both cores), but I have to  have
disable the splash.

Is this any hint for someone with deeper kernel/X/KDE knowledge?
