overcoming known kernel bug



Dear Debian User List,

I am having trouble with my 2016 lenovo thinkpad yoga 11e (3rd gen) running the current version of debian stable (stretch). The on wake-from-suspend the fan runs on high.

Specifically, I have:

~ $ uname -a
Linux tinkbox 4.9.0-4-amd64 #1 SMP Debian 4.9.51-1 (2017-09-28) x86_64 GNU/Linux

On wake-from-suspend:

  ~ $ sensors
  thinkpad-isa-0000
  Adapter: ISA adapter
  fan1:        6125 RPM

  acpitz-virtual-0
  Adapter: Virtual device
  temp1:        +65.0°C  (crit = +90.0°C)


The acpitz-virtual-0 pegs the temperature at 65°C and won't let it go. Therefore the fan attempts liftoff.

I could attach the output of 'reportbug kernel', but the problem is known and the bug is described in: 

  https://bugzilla.kernel.org/show_bug.cgi?id=196129

The bug is present up until it's fix in kernel 4.13.4 or something around that time. The solution is to install a much newer kernel (or downgrade).

Being lazy I tried to just install the latest backported kernel (linux-image-4.13.0-0.bpo.1-amd64). That doesn't work.

What I find most interesting would be to compile a slimmer, faster kernel, but I have failed (after consulting the debian kernel handbook). One thing or the other doesn't work afterwards. My idea was to use the old kernel configuration (with 'make olddefconfig'), but there are so many new options and I honestly have no clue how to get an overview and make an informed decision. 
I would report this as a low priority kernel bug but it's (far) upstream. It's also a known problem, which isn't necessarily debian's problem.

I would appreciate any advice. I bought this laptop because it's tough and has a good battery. Any laptop that misbehaves on wake-from-suspend is not a very useful laptop (Imagine a meeting with a constantly whining laptop). Thanks in advance!

Cheers,
Brian
