This is hard to reproduce(reason for looking a kmemchek).

As for what I remember, walked into the las Vegas convention cntr
(Hilton),
Found the Internet hub, scanned for networks, wicd said it was
connected, opened firefox to see the prices, ended up seeing a blank
page(at this point didn't look at dmesg(could have already happened)),
then switched to another network(did this a few times),
Eventually opened firefox(saw the prices, said fuc*k this), then
started to read up on i8042.c(cause Linus was pull requesting and I
wanted to find out what was going on in that area), then
Checked dmesg, and voilà there the bug is.

After this rebooted, was hoping this was reproducable for a bisect,
but realized it's not the reproducable..
