[Bug 327311] Re: Keyboard very slow after resume with Macbook 4.1

[Sebastian Thürrschmidt]

I also have a MacBook 4,1, currently running Lucid amd64, and I'm
experiencing this bug too. In fact, it's been happening ever since
Hardy, sometimes very frequently, sometimes only rarely, and always in a
very unpredictable manner. On my machine it's primarily the touchpad
that tends to be sluggish after resuming from suspend, less so the
keyboard (or perhaps I'm just using the touchpad more than the original
submitter).

I have a looming suspicion (but I can't prove for sure) that the
probability of a sluggish touchpad increases when an external USB device
(like a hard disk or an mp3 player) had been connected earlier during
the same session but wasn't any longer when going into suspend mode.
Also, in earlier Ubuntu releases (before plymouth), there were sometimes
text mode messages about interrupts not having been cared about while
resuming. Whenever one of those appeared the touchpad and/or keyboard
was certain to be unuseable.

I'd be happy to help resolve this bug. I don't have 50 euros to spare
(blame it on the MacBook), but feel free to ask for log files,
modprobing, lspci output, whatever.
