I have Intel Pentium N3540. It's known that Bay Trail line of CPUs has a system freeze bug which has so far been solvable by appending intel_idle.max_cstate=1 into a certain line of GRUB config, but this has stopped working since upgrading to 18.04.
Do you guys have any ideas why is it the case and if it is somehow fixeable? Thanks.
According to comment# 1013 in bug report it is now fixed:
I haven't checked this thread in a long time, but I thought I should post my findings just in case it is of any use to anyone.
A low end computer powered with an Intel N2807 which never worked more than 30 mn without crashing when I didn't set ...max_cstates=1 now works perfectly well with a stock kernel v. 5.3.1 or 4.19.75. I ran it for a couple of days with each version without any issues. The average power consumption was also down by a little over 10%.
It has taken about four years to fix this bug first reported December 8, 2015.
