Created attachment 118037 [details] grep(ed) drm out of dmesg Hi! I'm running Lubuntu 15.04 with open source radeon driver. Hibernating with systemd crashed, so I read this guide: https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt # echo freezer > /sys/power/pm_test # echo platform > /sys/power/disk # echo disk > /sys/power/state worked # echo devices > /sys/power/pm_test # echo platform > /sys/power/disk # echo disk > /sys/power/state crashed so according to the guide it seemed to be a driver issue. I started in recovery mode (command line) and pm_test worked as far as core- so hibernate worked. The modules that are only loaded during "normal" boot are: cfg80211 amdkfd amd_iommu_v2 radeon Even without cfg80211 hibernate crashes the system, so only radeon is left. So I booted with radeon.modeset=0 kernel parameter resulting in radeon not loading at all- but _hibernate works_! Then I booted with radeon.dpm=0 kernel parameter resulting in power_method=profile and profile set to default but hibernate does not work and crashes. For me it is obvious that this behavior is triggered by radeon driver. What can I do next?
