[Bug 555169] Re: Keyboard and mouse freeze after grub

[jhansonxi]

I tried -17, -16, and -15.  At first the keyboard worked so I went back
to -19.  It was working there as well so I powered off the laptop and
tried again and it failed.  It also was frozen in -17.  The -16 and -15
don't boot and end up in initramfs but the keyboard is frozen there as
well.  I powered off the laptop again then restarted and selected -19
recovery in Grub and the keyboard worked.  I power-cycled again and let
it start graphical -19 and it was frozen.  Tried -19 recovery again and
it was frozen.  A USB keyboard always works when plugged in.  Erratic
behavior like this would imply a timing bug of some sort.

I've also noticed that Grub doesn't always respond to the shift key at
boot as it doesn't show the menu and I have to restart again to make
another attempt.  It's possible the problem starts there but I have no
way to verify.
