Comment 35 for bug 334249

I can confirm on the Vostro 1510 as well, kernel 2.6.28-14-generic still has his problem.

Simply adding "i8042.reset" to my "kopt" section seems to have cured it, no need for the other options.

For me it was a little different - rather than 80% of the time it works - 80% of the time it doesn't. I would restart around 6, 8 times and nothing (on battery). If I would wait a period of time (an hour, maybe more or less) it would fix itself. Plugging in power might change things, sometimes didn't but it has some effect. Then again when it wasn't working and I was on AC, going to battery could fix it. Very odd, but nonetheless fixed and happy campers all around.
