For anyone trying to get this to work with more recent Ubuntu versions, I can confirm that setting the kernel option works for me on my Thinkpad T43 on Ubuntu 9.04.
Setting the max_cstate=3 was sufficient, and I am noticing little difference in power consumption (when idle with the lowest screen brightness I am at about 15W), so from my perspective this problem is solved. Applying the setting to /etc/modprobe.d/options did not work for me. -- Unable to set max_cstate on hardy kernel https://bugs.launchpad.net/bugs/206864 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
