Hi, on my Thinkpad T60 (2007-FUG), with kernel 2.6.21.1 I have the same problem Ingo Molnar had in January and successfully fixed for his model: http://git.kernel.org/?p=linux/kernel/git/torvalds/ linux-2.6.git;a=commit;h=e4233dec749a3519069d9390561b5636a75c7579 "Recently cpufreq support on my laptop (Lenovo T60) broke completely: when it's plugged into AC it would never go higher than 1 GHz - neither 1.3 GHz nor 1.83 GHz is possible - no matter which governor (userspace, speed or ondemand) is used." 2.6.21 and 2.6.20 include this patch and should not have this problem anymore. Is there any way I can see when ACPI calls for _PPC happen (via ACPI_DEBUG) and which _PPC values get returned? Which debug_level do I need? Here are some more people with the same problem on 2.6.20 and 2.6.21 (which includes that patch too): https://bugs.beta.launchpad.net/ubuntu/+source/linux-source-2.6.20/ +bug/88899 Thanks, Tobias - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
