After upgrade to Kubuntu 12.10 booted also without problems. Upgrade from 12.10 to 13.10 did not work so I installed 14.04 new. Install 14.04 from USB-Stick rebooted after a few seconds. If I do nothing or select install and try everytime after a few seconds reboots. After adding radeon.dpm=0 to bootline install works fine. First boot of installed kubuntu 14.04 reboots again after a few seconds. Adding radeon.dpm=0 to bootline system boots fine. Now added radeon.dpm=0 to /etc/default/grub:GRUB_CMDLINE_LINUX_DEFAULT and works fine, send ubuntu-bug linux from that PC with that CMDLINE.
