Same problem here. Ubuntu 10.10 (upgrade from 10.04) on Thinkpad T60 with ATI graphic card. Linux ubuntu 2.6.35-24-generic #42-Ubuntu SMP Thu Dec 2 01:41:57 UTC 2010 i686 GNU/Linux
Its the only thing that still bothers me about my Ubuntu installation and its the worst I had to face .. ever. I tried almost everything: - ACPI settings (BIOS) - TLP (Software to handle Thinkpad ACPI settings) - Pulse Audio deactivation and use of ALSA again .... fixed it for a long time I thought - WLAN ?? tried several drivers .. still an open point - ATI graphic card ... I am using the GPL drivers with "options radeon modeset=0" Dec 16 11:53:09 ubuntu kernel: [10378.753076] padlock: VIA PadLock not detected.
