Public bug reported:
My computer is unusable because of bug 1848771, which causes reset on
waking from suspend.
(that such a bug could slip through to a release in the first place is
beyond my understanding. Don't you guys test anything?)
Being unable to suspend means being unable to use the computer. Don't
tell me I can avoid suspending because (1) seriously? and (2) what if I
forget and suspend by accident? Loosing all my data is a
disproportionate punishment.
So, since the bug seems to affect kernel versions 5.1 and later, I
thought I could boot with an earlier one.
I am not familiar with booting with different kernel versions (because
why should I), but Grub's boot menu has an option "Advanced options for
Ubuntu" (or something like that) that opens a submenu where apparently I
can choose a linux kernel version.
A few in the list are post-5.1. The latest available that is pre-5.1 is
3.19.0.43-generic
So I tried that one, but all I get is a black screen saying "Loading
liunux 3.19.0.43-generic something..." and a blinking cursor.
I waited a few minutes and gave up.
