This report will only focus on the hardware noted in the Bug Description. If you have other hardware having issues, please file one bug report per machine via a terminal: ubuntu-bug linux Despite this, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-3.15-rc2 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-2102 ** Description changed: - I've noticed after installing Ubuntu 14.04 on a Richland APU desktop, that this critical DPM issue has still not been fixed. DPM needs to be disabled by default like in kernel 3.14 for these systems so that the live CD or desktop session does not instantly reboot the machine. I was able to bypass it by editing the grub.cfg on the bootable flash drive and adding radeon.dpm=0 to the boot options, along with cding to /target/etc/default and editing grub with the same change before rebooting after installation to bypass it. - --- + I've noticed after installing Ubuntu 14.04 on my computer, that a DPM + issue exists.
