There is no need to update grub anymore if you switch to a most recent kernel.
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.
