  • EC logged in S7, runin 0.17.0 or 0.16.7 (not C2 builds) if possible

  • If you have enough systems, try using stock runin 0.17.0-style settings as well as anything known to cause particular types of failures. (EC failures seem to be common within a few hours with 10s on/10s off suspend, only using runin-main/gtk/common/tests/sus/battery.)

  • http://dev.laptop.org/git/olpc-kernel/commit/?h=arm-3.0-wip-wfi&id=46e079fe
  • EC logged in S7
  • Should fix the hang caused by suspend being aborted due to a wakeup event. May also help with other IRQ hangs as I have fixed a previous mistake I made when moving the audio island code.
  • Testing aborted suspends can be done by running this command and then hitting the keyboard right away.

echo $(cat /sys/power/wakeup_count) > /sys/power/wakeup_count && echo mem > /sys/power/state

  • testing by
    • James Cameron, with a local debugging patch, saw one instance of eMMC "error -110 sending SET_BLOCK_COUNT command", on C1 SKU201, see log tail, and several instances of the hang in dpm_resume().
