Typing freezes the screen temporarily

[aneganov]

Please someone help! I have to reboot every 30-40 minute, since keyboard hangs and its impossible to continue working. I'm pissed off with this, I have to work but can't due to this!

When I type letters, and keyboard freezes, which happens every 2 seconds or so, sometimes typed keys are missed. This makes it even impossible to type blindly, guessing letters will appear after freeze.

I don't know is this related to freezes or not, but every time when this happens, logs are filled with this messages:

Help

[afauno]

I have the same issue after upgrading to natty...

It seems the same as this ubuntu bug https://bugs.launchpad.net/ubuntu/+s...ux/+bug/578506

More importantly, a patch is proposed by the kernel guys at https://bugzilla.kernel.org/show_bug.cgi?id=14733
