Of course you get high temperatures then. Do you use another graphics driver? It could be that it's the graphics card producing the heat. The binary one should be the first choice. How does this tool read out the temperature? Do you have any hwmon drivers loaded?

Ok, I have made a fresh install with M6 DVD i86-64 with kde4 Desktop. Added temperature applet from Kde4. It shows direct after start ca. 50°C Install of newest nvidia driver (binary) still the same.

Can you monitor how idle the system is if temperature is and stays high using top. You can monitor the frequencies of your cores in another terminal with: watch -n1 cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq Make sure your machine is really idle, the most important values in top are: X%us -> CPU load by userspace apps X%sy -> CPU load by kernel apps X%id -> The most important -> How idle is the core (should be more than 90%). If you have several cores hit the "1" to see each core listed in top. If you see a process which produces quite some workload, kill it. CPU frequency must get reduced and the temperature should be low. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I added them again one by one and it is... btusb What changed in 11.2 is that USB drivers are compiled into the kernel (ohci_hcd, ehci_hcd, uhci_hcd), it may have to do with that, it may be a change in btusb itself. Before looking further, can you try to reproduce and double check whether you have the same problem.

If I boot into "init 3" I already have high power consumption with 11.2.

I have some problems, but I can reach phones via bluetooth. Sometimes, but rarely, the consumption jumps up. It looks like some extra power saving code is active for 11.1 or 11.2 is really broken to let the device always run at some kind of "full-performance" mode. I am done with this problem for now. If someone wants to go on, you may want to use your battery (with AC unplugged) and monitor: cat /proc/acpi/battery/*/state and watch present rate: Let it give some time to update, but this could, depending on your HW, show you more or less fine grained power consumption differences (better than watching the temperature). -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Possibly I should summarize things in a new bug, the bug is already rather long and hard to read for others looking at it. I think I am also going to open another bug for the ath5k driver. I am pretty sure I see two regressions compared to 11.1. Eventually you can borrow a power meter from your local electricity company (some do that, at least in Germany). Possibly you see another fan behavior? Get the sensors package, run sensors-detect and sensors afterwards to monitor the temperature in a console, eventually you can also monitor fans with it. If you do cat /proc/cpuinfo do you see a c1e (or similar) flag in 11.2? Cpufreq should work fine, eventually it's also a device causing this? USB devices are known to keep the CPU busy, eventually you could do it similar than I did: Blacklist every low level device driver, then reboot and load them one by one and compare the power consumption. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This all is rather vague. Daniel: If you find out more and you can point us to a specific device or process running too often causing higher CPU utilization or similar, we can go on in a new bug, but currently it's hard to tell what the source of your problem could be. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Found this line: k8temp 0000:00:18.3: Temperature readouts might be wrong - check erratum #141 in /var/log/boot.msg This would also explain the spread over 10 points in sensors attachment and some other strange values. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I'd still like to keep this bug for btusb power regression tracking I am seeing. I expect this is related to: http://www.heise.de/open/artikel/Kernel-Log-Was-2-6-32-bringt-1-Die-Neuerung... Translation of the related topic: ------- The btusb driver is now usb autosuspend capable. On bluetooth chips which do not support remote wakeup, the interface must be de-activated for power saving mechanisms to take place. ------- We are still at 2.6.31 and something broke there for my chipset compared to 11.1 kernel. If I find the time I go on with this one, first try probably will be a 2.6.32 kernel. If anyone else is also seeing this and/or knows more about it, please point me into the right direction and I can add things if it's not too intrusive. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

At some time I am going to set up a measurement device on my private machine again and double check... -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
