Finally I decided to work with Ubuntu and report a bug with them: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1280668 The issue remained after updating all applications and after updating the kernel with the newest upstream mainline kernel: ~kernel-ppa/mainline/v3.15.2-utopic The system freezes for long periods of time and makes the computer unusable. Also, I can't boot this computer normally because it freezes with a black screen. The only way to complete the installation process was passing noapic as a boot parameter. The PC still hanged but for shorter periods of time and then continued working. With Ubuntu I tested installations with several versions and I found the following: . Ubuntu 10.04.4 LTS (Lucid Lynx) was unable to boot the PC due to a Kernel panic. [0.812538] Kernel panic - not syncing : AMD-Vi : ILLEGAL_COMMAND_ERROR while resetting command buffer . Ubuntu 10.10 (Maverick Meerkat) was unable to boot the PC due to a Kernel panic. But I wasn't able to capture the error. . Ubuntu 11.04 (Natty Narwhal) was unable to boot the PC due to a Kernel panic. And I wasn't able to capture the error. . Ubuntu 11.10 (Oneiric Ocelot) was able to boot up and hang up for more than 20 minutes. I wasn't able to work with the computer or get any logs. However, the last message in console was: [147.992078] AMD-Vi : Completion-Wait loop timed out It seems that the problem appeared for first time in the Ubuntu release 11.10 (Oneiric Ocelot), because with previous Ubuntu versions this PC was unable to boot.
