With ACPI enabled kernel may hang in a day or in a week (never survived more than approx. 2 weeks). With acpi=off it seems to work OK. For instance, I had to boot Ubuntu installer with acpi disabled to finish it successfully. Usually, hanging is not accompanied by panic log. Only small vertical red lines appear on the screen near letters (tried to use plaintext 80x25 console without radeon and got the same issue). Still observing this for 3.16 kernel.
