Hello, could you please share crash dump /sys/class/drm/card0/error? Does It still happens if you remove this parameters?: enable_rc6=1 enable_fbc=1 semaphores=1 enable_guc_loading=1 enable_guc_submission=1
The system kernel now is updated to 4.15.5-1-ARCH and Mesa is updated to 17.3.5, the issue is still present. dmesg1 https://pastebin.com/hJuET9aN This is the dmesg with all parameters included dmesg2 https://pastebin.com/TU4h1C9G This one is the one after removing the parameters Either way I always get "No error state collected" from /sys/class/drm/card0/error

Could you try dmc 1.27 https://bugs.freedesktop.org/show_bug.cgi?id=101991#c18?
Created attachment 137628 [details] dmesg custom kernel with dmc 1.27 Same issue with dmc 1.27
Does the problem happen when booting without any of the following options: acpi_rev_override=5 pci=noaer acpi_osi=! acpi_osi="Windows 2009" acpi_osi=Linux libahci.ignore_sss=1 pcie_aspm=force pcie_port_pm=off intel_iommu=on Could you provide a dmesg log containing the same error booting with drm.debug=0xe ?

Yes the problem still happens
(In reply to amn-bas from comment #8) > Yes the problem still happens Thanks. Something is strange with your config, could you check that?: [ 118.921490] [drm:skl_check_plane_surface [i915]] requested Y/RGB source size 7680x4320 too big (limit 8192x4096)
Hmm, so I enabled early KMS and disabled all i915 options from /etc/modprobe.d and booting only with these parameters root=UUID=fdcdfaf9-f530-4274-a064-f697b811d9f4 rw resume=/dev/nvme0n1p2 resume_offset=34816 drm.debug=0xe I tried comparing Arch LTS 4.14.22 with dmc 1.26 and a custom Arch 4.15.6 with dmc 1.27. The LTS one resumes fine after hibernation but with errors. "requested Y/RGB source size 7680x4320 too big" is not there. LTS dmesg: https://pastebin.com/kA23prNc custom dmesg: https://pastebin.com/iTxu6Rh7 The same config is used for both, I am using TLP and powertop for power saving you think they might affect that?
I updated the mesa driver to the latest version on Archlinux repos 17.3.6 and now booting with LTS kernel (4.14) resumes without any errors. With 4.15 I'm still getting a black screen and a bunch of errors. I noticed that with 4.15 the screen backlight flashes after resuming something like if I set the backlight to 100% then to 30% and it does that for 2-4 times.

Could you provide a full dmesg for the 4.15 boot (booting with drm.debug=0xe and making sure the dmesg log buffer is big enough to contain the PM: hibernate/resume sequence too)? It'd be great if you could also try the drm-tip branch from git://anongit.freedesktop.org/drm-tip .

Created attachment 137791 [details] [review] Fix hibernation with S0 target state > Created attachment 137788 [details] > dmesg custom 4.15 w/dmc 1.27 There's the following: [ 64.041878] Unexpected DBuf power power state (0x0000000a) during resuming. One possibility is that hibernation happens with an S0 ACPI target state (or at least target state < S3) and because of that we won't reinit power domains during resume. That's a failed attempt on my part to fix this issue in an earlier patch. Could you try the attached fix on top of 4.15.6 to try it again (and attach a log)? In the log there is also the [ 69.146901] [drm:skl_check_plane_surface [i915]] requested Y/RGB source size 7680x4320 too big (limit 8192x4096) error, that one looks like user space asking for an invalid config and unrelated to the above.

This one is strange because I don't see that with 4.14, it shows only with 4.15.

Created attachment 137899 [details] 4.15 with debug patch

But I can't see in your log any of the debug messages that I added in my debug patch. Could be that you are using the wrong kernel (you can cross-check your booted kernel's version with your git repo by enabling CONFIG_LOCALVERSION_AUTO) or you didn't update your initramfs.
Created attachment 137920 [details] dmesg patched I'm really sorry I'm using arch build system to build the kernel I've added the last two patches but I forgot to apply them in the build file so I was building the kernel without the last two patches LOL. However, after building it correctly the patch worked and I was able to resume from hibernation successfully.

Ok, thanks for testing it, I'll follow up with the fix and close this once it's merged.
Fix merged to drm-tip.
