Comment 10 for bug 65249

I have the same issue. Sometimes the system will freeze for a split second (keys typed don't echo on screen immediately) and afterwards all keys that were pressed during the freeze are echoed simultaneously with one of them repeating several times like this: hellooooooo
This will happen randomly over time. On some login sessions the issue is not present.
I have dual boot with Windows vista and the issue is not present in Vista hence I can confirm it's not a hardware issue in my case.
Please ask me anything else you need to know.

Here's some more information about my computer:
It's an HP tx1215nr laptop with an AMD Turion x64 dual core CPU.
I have a broadcomm wireless and I had to install it using ndiswrapper with the windows XP driver to make it work.
I'm using the International US English keyboard layout.
Compiz-fusion is enabled with wobbly windows and desktop cube and other eye candy. I also use gdesklets.
My Ubuntu version is Gutsy x86_64. My laptop will only boot using the options noapic and irqpoll.
