Title:
suspend crashes laptop
Status in linux package in Ubuntu:
Confirmed
Bug description:
Suspend stopped working when upgraded to kernel 5.3.0-41 from -40.
Power-button (narrow slit) LED stays fully lit and front indicator
power/wifi/drive LEDs also lit as though not suspended. Screen went
black but will not respond to keyboard/touchpad input (even Ctrl-Alt-
Del). Only way to recover laptop was long-press power button (5
seconds) to force it to turn off then press again as normal to cold
boot.
Also note: Builtin stereo speakers also stopped working in the same
kernel version change - out of scope for this bug I expect, perhaps
related to SOF or Alsa migration/integration changes I saw in
changelog: Builtin microphone never worked on 19.10, even after
researching issue and trying assigning each pin in turn to it via
hdajackretask.
Boot and shutdown and suspend and builtin speakers all working
normally in kernels from initial install of 19.10 in November 2019
through 5.3.0-40 (inclusive).
Laptop is an HP Elitebook 830 G6 with ProdId 6XE61EA#...
TRIED:
installed 5.3.0-42 (latest as I write) kernel, same result as -41.
Added "snd_hda_intel.dmic_detect=0" to /etc/modprobe.d/alsa.conf (about to
try it in alsa-base.conf instead)
Also tried live boot of daily snapshot of Ubuntu 20.04 from 12 March 2020,
fails to suspend and speakers not recognised (same problems). Kern.log and LEDs
strongly indicate machine crashes before suspend achieved (having read up on
the difference), so appears to be a suspend problem not a resume one;
especially as LED goes into dim/brighten cycle on previous kernels when it goes
into suspend and resumes fully with no issue.
Cancelling the suspend just after I've pressed the power button to suspend it
and the screen has gone black (think I used space key? or did I press power
again?) worked the one time I tried it, and dmesg/logs indicate a fair bit of
the suspend happens ok.
Appears to match part of this upstream issue (about an HP Spectre x360
laptop):

May have time to bisect some kernel changes or try other fixes or
build kernels/code, given a few days (am a software developer)
