Laptop unable to resume (only on Arch)

Uzytkownik · 2018-04-22 19:14:41

My laptop is unable to resume when I'm on Arch (doesn't react to Lid or to power button) but suspend works on both Gentoo and Fedora.

How is suspend configured on all three operating systems? What is the dmesg or journal output from a suspend attempt on all three systems and the same from resume / failed resume.
What do you do when the system fails to resume under arch?

I narrowed it down to intel_iommu=on parameter which worked on older kernels (I haven't used Arch in a while - 4.13ish maybe?) but it prevents suspend now. If I disable iommu than iwlwifi fails to load due to memory ranges so I don't have network. pm_trace does not work as BIOS detects corruped RTC and corrects it. iwlwifi is not itself cause of the problem as suspend fails even when it is loaded.

If it helps I noticed that while the power button is flushing (as it should) and keyboard buttons (such as mute) are lit (as they shouldn't).

On Fedora I used default settings. On Gentoo I think I have just blacklisted e1000e which sometimes fails to suspend and causes resume but otherwise it is also mostly out of the box with systemd.

Failed logs end on:

Success is:

Though it might be because of flushing of disk.

I force reset (press power button for 15s) - what else can I do?

https://bugs.archlinux.org/task/58288 will be fixed in 4.16.4 then you can remove iommu=on

I forgot to add - Gentoo at least have iommu enabled which still makes it an Arch-specific issue rather than something in HW. As general I think IOMMU is good idea (secure-wise).

Is it the same kernel version for both arch and gentoo? Can you try building the arch kernel package with gentoo's config or a minimally modified version of it and see if that works?

Yes. linux-custom with config from Gentoo works without problems.
