I JUST got the "you have a new version available" and clicked update
last night. From ~21.xx to 21.10 and it won't come back from deep sleep.

Acer C740P laptop with Ubuntu desktop.

Switching to:

echo shallow | sudo tee /sys/power/mem_sleep

from the previous comment allows me to come back. However, I'm almost
certain this is a lesser level of suspend than WAS working on 21.xx
because now it comes back on _instantly_ and it never did it that fast
before. So I imagine that means my computer is barely suspended at all
in this mode.

The last line of dmesg was :

acpi: EC: interrupt blocked

using:
$ journalctl -o short-precise -k -b -1

to get the previous dmesg log. But that ACPI line may be innocuous and
not the key failure.

I'm not aware of any other useful log locations. Also a tool called pm-
suspend seem to sleep and come back just fine.
