On Manjaro stable release only.
Since at least the kernel 5.10 series, I had random perfect hangs of my PC systems based on Intel chips. No logs found to help.
- Intel NUC with i5-8259U CPU, systemd-boot
- Razer Blade Stealth with i5-7500U CPU, Grub
I patiently tested many culprits, and the following combo of kernel options stabilized my systems
rw noirqdebug pci=noaer idle=nomwait processor.max_cstate=1
Despite these set of options, energy managment features of the systems work, the energy consumptions are as low as usual.
Only a sab drawback, sleeping the laptop remove the touchpad movements on wake, but not the click/tap functions. I do not know how to reset the driver…
