Linux laptop freeze solution
I got a huawei matebook 14 few years back, installed Kubuntu, then switched to Manjaro recently. It freezes now and then without any pattern. At first I thought it is caused by audio driver, removed pulse audio didn't fix the issue.
then found the solution
sudo nano /etc/default/grub
add idle=nomwait
to the end of this line.
GRUB_CMDLINE_LINUX_DEFAULT="quiet udev.log_priority=3 pcie_aspm=off idle=nomwait"
save and restart.
