Comment 9 for bug 479839

Yes, I'm unsure if this is the same bug, but the keyboard intermittently stops functioning. Bug 555169 seems to address the mouse/touchpad not to work at all.

I've noticed that changing my system time will result in the trackpad on my lappy to die. I can keyboard over to the OK button and select it manually and strangely enough, touchpad functionality will return to me immediately afterwards.
