One of my PC:s is also affected by this bug!

I have a PC with MSI FM2-A55-E33 motherboard and a AMD A4-5300 APU, 4GB RAM.

Ubuntu 14.04 LTS 64-bit does not work on it either. Boot from Live-DVD fails after half boot-up, screen goes black and after approx 5-8 seconds the computer reboots and locks at EFI GRUB.

Any other recent Ubuntu works on this computer, the exception being U 14.04 LTS 64-bit. If I do a fresh U13.10 install it all works great, but if I do a dist upgrade from that U 13.10 to U 14.04 LTS the installation process works fine, but after the finalizing reboot it crashes seconds after the 14.04 Login screen appear, reboots and goes into locked mode at EFI GRUB. Hard Power Off is requiered.

I have reverted to U 13.10 on this machine for the time being while a fix is developed by some of you Ubuntu wizards..

/Per in Sweden

ps. I have another PC with a MSI motherboard, FM2-A85XA-G65, a AMD A10-6800K APU and 8GB RAM. But it seems to be working, did a dist upgrade from U 13.10 to U 14.04 LTS and it has not crashed yet after a couple of days. It starts, reboots and functions apparantly as normal.
