Hi all,
first of all i am not sure if its scheduler issue. But i didn't found
anything about that in google related to something else.
So i tried 2.6.22.1 kernel with new cfs scheduler v19.1 from Ingo page.
Previous i used 2.6.22-ck1.
After 24 hours running i get strange behavior in Xorg. It act slower
with my special keys, like SHIFT, or CTRL. So if i hold SHIFT and press
")" and than will press enter, i release SHIIFT and press ENTER it
doesn't create new line. Even if i start write a Sentence or word with
"SHIFTed" char it makes next char in high case also.
Like this: "HAllo" even if i type "Hallo".
It's extremely unusable.
It doesn't happen if i am on other kernel.
I am ready to provide any requested information to find issue.
If its not kernel related thing - i am very sorry, i just don't know
where to start to trace whats wrong.
I am on gentoo and use latest xorg server. Keyboard driver is "KBD".
Mouse use "evdev" driver.
Ingo, can you take a look at this?
another reaction below in this thread reported kbd problems in vanilla
2.6.22.1 as well. What is the X versions, etc.? Does the problem go away
if the X kbd driver selection is tweaked to a simpler model, say:
Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
Option "XkbVariant" "basic"
EndSection
Ingo

For a few days now I have been experiencing a "stuck delete" key while
reading mail -- I run through the mail with "delete" and every once in a
while it just keeps on deleting messages while I've already released the
delete key and was trying to read the next message.
Regular unpatched 2.6.22.1 though and I've recently changed too many things
to be certain of anything. My X is the modular X.org 1.3.0 since not long,
and the mailer showing the problem is Thunderbird 2.0.0.5, recently switched
from 1.5.0.12. The problem was on my "I'll get to it" list but seems this
could be a good thread to report it into. PS/2 keyboard...
It's extremely unusable.

Very very sure?
