Comment 6 for bug 346310

Matt,

I wouldn't be so sure about it being a kernel issue since, at least in my case, I can switch to a text console (Ctrl+Alt+F1) while the keyboard and mouse are unresponsive in the X session. If I Ctrl+Alt+F7 back, the mouse and keyboard still don't respond, but I can still switch back and forth to vt1. After some 28-29 seconds since resuming, they start working all right again.

Another thing that I've noticed is that this tends to happen only when I'm running on battery, and not when the AC adaptor is connected, but I have to test this last hypothesis more thoroughly.
