(Get the code!)
kernel 4.19.27 with rcu_nocbs=0-11 idle=halt nopti, yesterday at around 11:30 p.m. I had an "usual" total lookup of the system during light usage (I just had an ssh session opened). With idle=halt, I get no "ACPM WAIT C-state bug" line in dmesg.
The problem with this freeze problem is that is difficult to replicate. The segfault bug was very easy: 3-4 mesa compilations triggered it for sure. This bug, instead, can hide for days and days and it reappears all of a sudden.
