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?
