Symptom is a row of ^@ on the console.

Rebooting fixes this for a few hours again.

Any pointers?


(Sorry if I reply to the BTS in incorrect ways, it it is my first time.)

Bug 558656 had similar symptoms according to 
http://lists.debian.org/debian-user/2009/11/msg01695.html.


Could it be a related problem?
Are you using acpi-support 0.130?

Regards

Johan

Nothing wrong with your email :-)

It sounds like exactly the same.  So, since this is already reported, 
closing the bug.

 Are you using acpi-support 0.130?

Hmm.  No, acpi-support is still at lanny (strange); will try to update and 
see what happens then.  Hadn't tried acpi stuff earlier, but setting 
brightness and restarting acpid does trigger/stop the issue as described.

Thanks a lot!

cheers

Heyho!

Quite an annoying bug and no idea where to start looking...

On this Atom (AOA 150; kernel, hal, udev, X mostly from sid or at least
squeeze), I have now twice (both times after several suspend/wakeup cycles) had
the keyboard in X suddenly lose keyboard repeat.

I tried to set keyboard layout in KDE, didn't change anything.

Switch to console: appears normal at first, but after I enter the login and am
at the password prompt (or in some cases only after I entered the password) it
seems that null bytes are entering from the keyboard ca. 3 per second, which is
a lot slower than keyboard repeat, so it's not a stuck key.

Symptom is a row of ^@ on the console.

(and while typing this, I see that it seems to happen under X, too: since ^ is
a dead char, I need to hit the space bar real quick after hitting the caret key
or the caret will have been canceled.)

Rebooting fixes this for a few hours again.

SysRq unRaw keyboard doesn't help.

X has KMS enabled.

Any pointers?
