The patch above is only a part of the picture, it's actually the amdgpu driver that is at fault and causes the machine not to wake up, the Renoir support is in the works for it. More details here: https://gitlab.freedesktop.org/drm/amd/-/issues/1230
** Bug watch added: gitlab.freedesktop.org/drm/amd/-/issues #1230 https://gitlab.freedesktop.org/drm/amd/-/issues/1230 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1886937 Title: limited hardware support AMD 4700u HP Envy x360 13-ay003nd Status in linux package in Ubuntu: Confirmed Bug description: Suspend/Hibernate: screen goes off, nothing else happens. After user interaction, screen turns on. Login screen is shown. Sometimes screen does not turn on: physical reboot required. kernel upgrade to 5.8rc3 or 5.8rc4 has no effect. Brightness: Adjusting brightness has no effect, nightmode has no effect. Partial solution: kernel upgrade 5.8rc3 or 5.8rc4 solves this partially, brightness can be adjusted and nightmode works But after a reboot brightness is always at max. Also brightness cannot be lowered as much as normally expected. CPU & fan: CPU is always high, 5.8rc3 solves this partially, fan is still always on and quite high (after clean Ubuntu install, nothing configured or installed).
