073c7fbf - arm-3.0.17-wip

  • TTY: serial_core: Fix crash if DCD drop during suspend
  • EC logged S47 (if available)
  • os24 base image or one which does *not* have the new graphics ABI
  • purpose, test if fixes found in the 3.0.17 Linux kernel solve our issues
  • testing by
    • Samuel Greenfeld
      • 5xC1, all units passed 24 hours with 10s suspend cycles (with clock skews ranging from 10 minutes backwards to 20 minutes forward after being set via ntp-set-clock prior to the test). System reboot order and overall duration varied from the order & time amount I recall starting the systems with. Testing was done without runin-camera, although looking at the kernel configuration it may be possible to turn it on again.

  • testing by
    • Samuel Greenfeld
      • Seems to hang on all test systems within 2 hours with 10s suspend cycles (multiple failure modes, including #11528), possibly aggravated by sending serial data to the XO during the suspend/resume process. But failures have also been seen after rebooting systems and ignoring them.

  • 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().
