I think this might be related to the phone powering on the screen after
a notification. That is: I believe the occurrence is higher after the
phone has woken the screen (and perhaps then timed out), compared to
when there was no notification since I last used it. This is because it
seems to affect me more when I'm responding to something (eg.
notification LED with screen off) versus when I have taken the
initiative to use my phone.

I also haven't seen this since OTA-7, where other bugs related to screen
power seem to have been fixed.

Bug description:
  [filing here although may be other components]

  Mako running 211 from rtm
   I experienced these symptoms which have been previously mitigated in other scenarios.
  Last week while traveling and roaming this happened pretty much 100% of the time.
  This occurred in all areas (hotel, MWC, outside, etc)

  Press power button, no response
  Press button again, screen turns on for a few seconds then turns off
  Press button again, either phone resumes or more often the power dialog is shown

  When I returned back home the function was normal without reboot or
  other changes.

  The differences in environment:
  Roaming on foreign GSM network
  Lots of Wifi APs not connected

  Attached are some perhaps relevant logs, unfortunately the syslog
  rolled.
