Public bug reported: I'm using Ubuntu 9.04 (jaunty) on my IBM Thinkpad A21m now (700MHz Pentium III Coppermine, 440BX Chipset, piix4) Everything works fine. Speedstep ondemand is not working but I can switch between powersave (550MHz) and performance (700MHz) governor. I didn't do anything to be able to use it. I do not need any module parameters. It works out of the box. The speedstep modules are compiled into the kernel anyways. The cpufreq driver is speedstep-smi.
I tried Ubuntu 10.04 (lucid) these days. Speedstep doesn't work. The CPU is clocked to 550MHz. No way to use 700MHz. I tried to use different advices from thinkwiki: http://www.thinkwiki.org/wiki/How_to_get_SpeedStep_working_on_Coppermine-piix4-smi_based_ThinkPads#Ubuntu_.28Edgy.29 But because the modules are compiled into the kernel, I do not know how to give it the parameter "relaxed_check=1". I tried to add "speedstep-lib.relaxed_check=1" and "cpufreq.debug=7" to the kernel cmdline. In jaunty this gives me an error, lucid simply ignores this. (sorry for not using "ubuntu-bug -p linux", but this would be pointless because I'm in jaunty now where everything is working fine.) I will add dmesg, /proc/version and /proc/cpuinfo from jaunty and lucid ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- No speedstep on IBM Thinkpad A21m (P3 Coppermine) with lucid and 2.6.32 https://bugs.launchpad.net/bugs/580189 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
