I have F22 on my son's Optiplex 780 ultra-small form factor. We seem to have a variety of (maybe related) power management issues.

First, the fan often goes full-speed and starts making lots of noise. Usually this is when the computer is actually doing more work, like running Minecraft. Sometimes it happens when watching Youtube videos. Since these are the two main things he does with the computer, it pretty much always happens eventually.

Second, when this happens, and he then suspends the computer, the fan stays on during suspend. It never quiets down. So I don't think the computer is suspending properly.

Third, if I hibernate the computer, the fan shuts off, but the computer actually shuts down--when he returns from hibernation, he has to log in to a new session, his apps have all shut down, etc.

I used to use this computer (several years ago--it was probably F16, maybe 18) and I don't recall these issues, so I believe they must be fixable.

I tried installing TLP, not expecting much from it on a desktop, but figuring it wouldn't hurt, and it didn't appear to change anything.

Any advice about where to start with this?

Thanks, Matt

Well on the hibernation side resuming from hibernate is currently broken in Fedora (all releases) but fortunately there's a trivial workaround to fix it.

Thanks! Either I did something wrong, or it didn't work. swapon -s gives /dev/sda6, and after grubby I see a grub.cfg (in /boot/efi/EFI/fedora) that has a "resume" entry like this:

linux16 /vmlinuz-4.4.6-201.fc22.x86_64 root=UUID=71f05257-0f3f-456c-a5b5-d2d60acb5cec ro /dev/sda6 resume=/dev/sda6

in the ### BEGIN /etc/grub.d/10_linux ### section.

Below is my whol grub.cfg, in case that helps.

Any other ideas?

Thanks, Matt

So memory must be 98% or less than swap free, not swap partition size.

You're best off using UUID. It needs to be in /etc/fstab UUID=theuuidforswap swap swap 0 0

In /etc/default/grub GRUB_CMDLINE_LINUX="resume=UUID=theuuidofswap" grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg ## for efi systems and just /boot/grub2/grub.cfg for BIOS

Chris I'm pretty sure one of the initial things that came up with that bug is that the systemd hibernate generator didn't work with UUID and the direct path (via devmapper if required) was needed.

No swap volume UUID definitely works in my case, it resolves it to the correct major:minor. It just fails validation for some reason.

My understanding of systemd hibernate generator is it doesn't work with GPT partition type GUID for Linux swap, which is a fixed UUID, 0657FD6D-A4AB-43C4-84E5-0933C84B4F4F. And the reason is they think it's unreliable to just assume that's where the hibernation image is, using the generic swap GUID rather than an actually unique one for the specific swap that should have the hibernation image. At least that's my understanding of the systemd list thread. They did say it would be reliable to use an attribute setting for the partition, which is part of the UEFI GPT spec. But parted doesn't support arbitrary attributes or GUIDs for that matter, so we're kinda stuck, and that solution doesn't work on MBR partition disks.

Further, there's still the open question whether it's OK for the hibernation image to be on an LVM LV. If it should not be on an LVM LV, then that means a more substantial change to Anaconda to support it that results in only root fs on LVM, at which point the can of worms that's opened is, why not just drop LVM from Workstation? I think without a clear statement from Harold or the LVM folks about hibernation images on linear LVs, it's questionable whether it's really correct to add resume=/dev/mapper/fedora-swap for everyone. For all we know this causes at least as many problems, or even worse it might be silent problems that don't materialize until later on; where failure to hibernate/recover is brutal enough the user is going to quickly figure out it simply doesn't work.

Chris can we keep discussion of the bug itself to the bugzilla entry and not infiltrate a random user support thread? ;)
