Issues resuming from hibernation
I've got a debian stretch installation on a MacBookPro 12,1 (Retina, Early
2015). When I resume the system from hibernation, the Wi-Fi adapter doesn't
work any longer. I need to reboot the system to have it work again.
Besides, performance in general is pretty bad after resume. The system is not
responsive--e.g. windows in the desktop environment take tens of seconds to
open.
I've got a 7.5 GB swap partition (7812496 KiB), and 7.7 GiB of memory (8079104
KiB)--actually I chose 8 GB for swap during disk partitioning, but I didn't
get what I wanted, perhaps because of the giga vs. giga-binary thing.
After a first installation attempt, where I had just 3 or something GB of swap,
resume after hibernation didn't work at all. I got messages like the
following:
PM: Image loading progress: 0%
PM: Image loading progress: 10%
PM: Image loading progress: 20%
PM: Image loading progress: 30%
PM: Image loading progress: 40%
and then a black screen.
So I repartitioned the disk, increasing the swap partition, and reinstalled.
Now the system does start from hibernation, but there are the issues I
mentioned.
I hope it's not related to a swap partition slightly falling short of RAM.
Reinstallation is not an option now!
Please let me know what information I should provide, so that you can tell me
what I need to analyze.
Thanks!
