[Bug 361123] Re: Lenovo T61p is running very hot after Jaunty upgrade
I found this bug because my t42p was running very hot with Jaunty (I was running Debian/Sid before). After looking around for a while, I noticed that the processor was running at 2 MHz all the time, that is, that the cpu frequency governor was set to 'performance' by default in the kernel. I solved the issue by putting: echo ondemand /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor in /etc/rc.local It really doesn't make sense to have 'performance' as the default governor for laptops!

[Bug 361123] Re: Lenovo T61p is running very hot after Jaunty upgrade
Ok. I found a workaround. 1. you can monitor your fan speed from the thinkpad-acpi module: cat /proc/acpi/ibm/fan 2. you can adjust the fan speed to stay on at full speed by executing the following command as root: echo level disengaged /proc/acpi/ibm/fan One I did that, the fan kicked up to 4000+ rpm and stayed there. The CPU temp stays at 94C under full load and goes no higher. For more info, see the following: http://www.thinkwiki.org/wiki/How_to_control_fan_speed Good luck! -- Lenovo T61p is running very hot after Jaunty upgrade https://bugs.launchpad.net/bugs/361123 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
[Bug 361123] Re: Lenovo T61p is running very hot after Jaunty upgrade
does anybody know, where/how are thresholds managed, when and how much processor speed should be stepped up when they are busy enough? is there any changes made between 8.10 and 9.04? all the time i was running boinc client under 8.10 and cpu were set to ondemand and no matter what other processes i ran, boinc had no effect to processor speed changes. it just used nice-ly, whatever time processor was idle. only us/sy -processes affected processor speed changes in ondemand mode. under 9.04, in the other hand, one can stop all the other programs and leave only boinc running and processor speed will jump up and down way too often, staying on top speed too much and heating up the machine. stopping boinc and running my ordinary set of user-programs, speed changes behave normally, stepping up only when i load some website in firefox etc. even tweaking boinc to use only 70% of processor time (used to be set to default setting under 8.10, which was probably 100%) will not restore the usual relaxed way this machine/os/programs used to run. -- Lenovo T61p is running very hot after Jaunty upgrade https://bugs.launchpad.net/bugs/361123 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
[Bug 361123] Re: Lenovo T61p is running very hot after Jaunty upgrade
could it be, that becuase for whatever reason 9.04 changes speeds of two cores independently, it also evaluates busy/idle thresholds independently? say, threshold for jumping up the speed is/was x (whatever unit of whatever measurement) and when proces...@8.10 reached this threshold, speed was stepped to next available speed... at 9.04 the same calculation is applied per core basis, therefor same threshold is twice as frequently/easily just a thought anyhow, nice -stuff should change nothing in this department, no matter how these changes are calculated. -- Lenovo T61p is running very hot after Jaunty upgrade https://bugs.launchpad.net/bugs/361123 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

CharleyS, I didn't specifically do anything to fix the problem but, if memory serves, it went away after an 'apt-get upgrade' about a week before Jaunty hit release.

[Bug 361123] Re: Lenovo T61p is running very hot after Jaunty upgrade
Thanks for the response. I just came home to my cold laptop. I booted Windows XP SP 3 and ran a prime number calculating application against each cpu core. They ran to 100%, 2.5GHz each, and the temperature averaged right around 90C. I could feel the fan spinning up and pumping heat out of the laptop. I shut the laptop down and booted the kernel referenced in my first post. I ran the stress app mentioned above, without the io argument. Both CPUs immediately hit 100% and 2.5GHz, the temperature *immediately* went to over 100C - This is a fairly new laptop, the fan is clean. I can't believe I'm the only one still having this issue, or that it has been fixed... I HATE saying it works in Windows - but sadly, it does.

I am experiencing the same issue on T61 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:58:03 UTC 2009 x86_64 GNU/Linux If I leave a background application running (boinc client, sbackup) the laptop overheats and shuts down. I have the cpus throttled back from 2.5 GHZ to 800MHz. Currently running sbackup the cpu temp is 85C. If I run the CPU at 2.5GHz the temperature begins to climb and eventually the laptop shuts down.

seems like cpu freq applet has suddenly started modifying cpu speeds independently for two cores... i kinda remember that at 8.10 changing one changed the other too. something seems to be changed with thresholds too, setting both cores at ondemand and running my usual set of apps, machine still runs little bit hotter than it used to run just few hours before, at 8.10. way too often one or both cores jump up to 2G. only setting both cores to 800M, will the temp go down to the level where it used to run at 8.10/ondemand. looks like month old issue, will anybody start being more than undecided, please? -- Lenovo T61p is running very hot after Jaunty upgrade https://bugs.launchpad.net/bugs/361123 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
