Re: [PATCH] Reset ps/2 port should psmouse_probe fail before retrying

["Peter M. Petrakis" <peter.petrakis@canonical.com>]

Hi,

i8042.reset=1 was one the first things we tried and it didn't
improve the situation. Now looking at the code for
i8042_controller_reset, I don't recall seeing these printks
though I could double check. Any other suggestions for
resets or instrumentation? Thanks.
