["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Dean Henrichsmeyer, the next step is to fully reverse commit bisect from
kernel 4.4 to 4.5-rc3 in order to identify the last bad commit, followed
immediately by the first good one. Once this good commit has been
identified, it may be reviewed for backporting. Could you please do this
following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

After the fix commit (not kernel version) has been identified, then
please mark this report Status Confirmed.

Thank you for your understanding.

Title:
  Adaptive keyboard breaks with sleep/resume

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have a Lenovo X1 Carbon Gen2. It as the adaptive row of keys that
  change from function keys to volume, etc when you toggle the function
  key. It's always worked fine but with this kernel, after a few
  sleep/resumes, the entire row will go black. If I reboot it will
  return to normal. dmesg throws a bunch of these..

  [29190.142959] thinkpad_acpi: EC reports that Thermal Table has changed
  [30910.489925] thinkpad_acpi: unknown possible thermal alarm or keyboard event received
  [30910.489931] thinkpad_acpi: unhandled HKEY event 0x60c0

  though I'm not sure it's the cause of the failure.
