Console debugging output doesn't always resume on key press

[PieterPanman]

When I boot my system with console debugging output enabled from the boot menu, it stops after each page, which is excellent. When I hit enter on the first few pages it always continues to the next page. However, after a few pages I actually have to hit any key many times to make it continue, it just doesn't seem to register the key press. I usually just hold down the space bar until it continues, which may vary from 1 to 5 seconds. Attached is my lspci from linux. What else may be useful to help debugging this?

I guessed the trac component, please change as you see fit.

Oh right, didn't see that one, my bad. You can close this one, I'll leave a note at #2918 referring to this ticket. Thanks Adek.
