Bug#559414: general: Strange keyboard problem

Package: general
Severity: normal

Hash: SHA1


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?
