--- Comment #8 from Anisse Astier anisse@astier.eu 2011-11-03 09:17:28 PDT --- As I said to Alex on IRC, these patches also solves the issue on Toshiba laptops: C670D-10C (AMD E-240) and C670D-11K (AMD E-450). (Old reference: https://bugzilla.kernel.org/show_bug.cgi?id=34822 )
Just putting that out there.
