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. ** Attachment removed: "AlsaInfo.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1338275/+attachment/4146745/+files/AlsaInfo.txt ** Changed in: linux (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1338275 Title: [radeon] suspend fails in 14.04 with Juniper and Caicos on an Asus P6T SE To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1338275/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
