[radeon] suspend fails in 14.04 with Juniper and Caicos on an Asus P6T SE

[skomorokh]

Suspend to RAM fails for me with the radeon driver and two cards on an Asus P6T SE motherboard: Juniper and Caicos. Even at console in single user mode (to eliminate Xorg) and with "echo devices > /sys/power/pm_test" and "echo freeze > /sys/power/state" to narrow it down to unloading modules (it works with "freezer" sent to pm_test).

Unloading the radeon module (needed to blacklist with a kernel parameter first) lets everything work.

Tried the stock Ubuntu Trusty 3.13.0 kernel and also tried using 3.14.10 and 3.15.3 from the PPA. All fail, but 3.15 has the screen go white after a bit so that's new.

Tried installing various new X stuff that probably is totally unrelated via ppa:oaibaf/graphics-drivers

Tried disabling dpm with the radeon.dpm=0 parameter.

Tried disabling synchronous suspend with "echo 0 > /sys/power/async".

Not sure what else to try?

I'm still lacking the dmesg of when things go wrong, could you attach that?

[skomorokh (skomorokh)]

The /var/log/dmesg.log.1 file doesn't seem to be updated in single user mode, but it doesn't get any extra output from the suspend when it is.

Or are you looking for the output of dmesg at boot from each of the various test runs I did? I gave it a quick go on 3.13.0-30-generic in single user and dumped the output of dmesg to a file for you first.

(NB: Not sure if my NFS shows up there but the very first thing I did for the above tests was temporarily purge the nfs-kernel-server and make sure the modules weren't loaded (checking lsmod | grep nfs) since I actually suspected it first before radeon. However I've since restored that and it'll be in this log.)

[skomorokh (skomorokh)]

Turns out the problem was a line in rc.local where I was forcing the GPU into low power mode:

echo low > /sys/class/drm/card1/device/power_dpm_force_performance_level

Took out the kernel parameters and ran in single user but didn't catch that. Leaving radeon dpm on auto or setting it to high won't affect suspend but forcing it to low causes this freeze.

Closing the bug here because I assume it's a radeon driver issue and not at all Ubuntu specific.
