[Bug 1520965] Re: Lenovo Helix does not wake up from suspend


Regarding your question about different releases: The Lenovo helix
requires kernel 4.2 and above (otherwise it does not detect its
keyboard). So I can not say anothing about pre 15.10 releases.

As I said above, the problem also occurs with Debian testing.

You received this bug notification because you are a member of Kernel

  Lenovo Helix does not wake up from suspend

Status in linux package in Ubuntu:

Bug description:
  System goes to sleep, indicator does flash slowly as expected, but
  there is no way to wake up (Power Button, Lid open, Enter, ...). The
  only way to recover is to press power button for more than 4 seconds,
  and then power on again. pm-hibernate does work.

  Problem appears with 4.2.0-18-generic kernel, also with 4.4-rc2 (also
  under Debian testing kernel 4.2.6-1)

  Problem appears with terminal pm-suspend (with and without X running),
  lid close suspend, gui suspend.

  The “resume-trace” yields the following magic:
  [    2.228057]   Magic number: 1:0:0
  [    2.228158] rtc_cmos 00:02: setting system clock to 2001-01-01 00:00:18 UTC (978307218)

  (while without resume trace it says
  [    2.226884]   Magic number: 7:269:577
  [    2.226985] rtc_cmos 00:02: setting system clock to 2015-11-30 09:33:06 UTC (1448875986)

  The content of /proc/acpi/wakeup (with 4.4-rc2) is the following:
