Package: base
Severity: normal

I'm running debian-stable (etch) with the latest kernel (linux-image-2.6.18-5-686).

Cpu: pentium 4 (single core, no hyper-threading (no bios option)).

Box: Dell Optiplex GX260

uname: Linux pumpkin 2.6.18-5-686 #1 SMP Sat Dec 1 22:58:58 UTC 2007 i686 GNU/Linux

Symptoms:

The keyboard behaviour is usually correct, but when I press a
key with involves some cpu calculation (more than displaying
the key), then the systems behaves like if the key was not
released (at the time I release it). It is seen released
"later".

Some examples: the key is ctrl-T under firefox (I get tons of
new tabs), or / (slash) under firefox (when searching in a big
page), ctrl+ (this is horrible, I get a one huge letter after a
while on my firefox window with this), 'enter' in dselect on
the search line (in a search pressing / in the package list), ...

This does not happen in text-mode-virtual-console (with
dselect).

This happens ONLY with 2.6 (any version from 2.6.15 up to
2.6.18), I have NO problem with an old 2.4.27 (compiled
myself).

This happens with PS/2 keyboards and USB keyboards.

What I tried:
Lots of combinations of acpi=off noacpi nosmp noapic nolapic
notsc irqpoll noapictimer...

What I did not try:
Recompile a kernel with no smp and/or other PREEMPT config (the
one shipped with Debian has SMP and CONFIG_PREEMPT_NONE=y)

For now I'm using this script where the list of number are
keycodes which match the keys for which I want to enable repeat
(backspace, del, arrows for now):
-----------
#!/bin/sh
xset r on
for i in `xmodmap -pke|awk '{print $2;}'`;do
        xset r $i
done
for i in `xmodmap -pke|awk '{print $2;}' | egrep -v "98|102|104|100|22|107"`; do
        xset -r $i
done
-----------

It is my office's PC so I have no much time to try everything.
But if one tells me something to try, I'll do it.
I can live with this for now, but I'd prefer find a good solution.
I do not know wherelse to put my bug report apart from
"base".

Great. And closing the bug for real, Brice forgot to add “-done” to
the mail address. ;)
