Bug Description
The laptop doesn't get to sleep anymore, but it did around 3 months ago, so it might be a kernel-related bug. Here is the syslog extract after running "sudo pm-suspend":

Oct 14 11:01:33 cherry kernel: [ 3387.670350] sd 2:0:0:0: [sda] Starting disk
The important line here seems to be
Oct 14 11:01:33 cherry kernel: [ 3387.600155] legacy_suspend(): pnp_bus_

Actually the answer is here
https:/ /lkml.org/ lkml/2011/ 2/20/18
But I think it should be detected/supported by Ubuntu
