Bug Description
When I cold boot my Dell Vostro V13, the keyboard behaves as expected and I can properly type text without any issue. However, if I suspend the laptop and resume it, then keypresses feel laggish (each keypress feels like a few milliseconds behind), and some keypresses are left.
I'm not sure at all this bug is in the kernel, this was my best guess, feel free to re-categorize. You'll see in the Apport report I'm running Lubuntu, however I tested standard vanilla Ubuntu and confirm I have the exact same problem.
To give you an idea of how unpleasant and frequent this issue feels like, below is the text of my bug report, before fixing the characters missing because of this bug.
This is a Ubuntu kernel version regression from:
2.6.35-
2.6.35-26.46 BAD

Hi, glad to see this bug confirmed. How can I help you isolate the cause of this bug? I don't know much: sauce? upstream? regression? since when? are all unanswered questions.
What should I test first? I'm kinda lost here, to be more efficient I'd appreciate a suggestion for a test plan rather than just trying random tests :)
Thanks!
