A bit late in the day, but the 14.04LTS install fails on my system too, except if I edit the boot line at CD start up, adding "acpi=off". Then it starts sweet as a nut. Oh my system is a AMD A8 6600k with Integrated graphics | MSI-FM2-A55M-E33 Motherboard
I will add comments on system usability when the install finishes -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1309578 Title: Ubuntu 14.04 suddenly reboots when booting from Live USB AMD A8 6600k Status in linux package in Ubuntu: Incomplete Bug description: *PLEASE READ FIRST BEFORE MAKING COMMENTS* Please be advised if you are not the original reporter Sangeet Khatri, making comments here (ex.

Any further attempts in installing it resulted in the same bug. As soon as I open the "Ubuntu installer" application and click "Continue" button then the system restarts after 2-3 seconds. I asked the same on AskUbuntu and some more guys reported the same problem with AMD APU, so I believe it to be a genuine bug and not just with me. The BIOS version is the latest one downloaded from MSI official website which is version 11.5. Also an Interesting thing is that this bug is common with the latest iso of Arch Linux too, but when booting older distros like Linux Mint 16 from USB, then everything works like it should, so it might have something to do with the newer 3.13 Kernel version. I am not an expert, but I can surely tell that only the newer distros are affected by this bug as reported by some other guys at AskUbuntu and the fact that Arch which is running the newer Kernel is having the same bug, so it probably has something to do with the newer Kernel, but I could be wrong. This bug is not letting me install Ubuntu 14.04 on my hardware and it is affecting a few more users too. Here is the AskUbuntu thread : http://askubuntu.com/questions/449391/unable-to-install-ubuntu-14-04 -pc-restarts-after-i-click-continue-button-in I hope this gets fixed soon or with the 14.04.1 upcoming July release.
