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. Also, I run out of disk space lately (15Gb is huge!) 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
