some info: uname, lspci -vvv, lsmod, lshw
OS: Debian sid/testing (7.0)
PROBLEM ON KERNELs: <=3.8.3
I always suspend (command pm-suspend) system instead shut it down. Sometimes (1 of 10 times) when I wake my computer, the temperature of CPU is high. It is ~60°C instead ~48°C (normally). htop shows that every processes is less then 4% usage of CPU so this is not problem with system (I think).
I also upgrade my bios to the newest version (download from lenovo website) but problem is still enable. I don't use another OS so I can't detect a source of problem (hardware or software).
How to fix:
Suspend and wake system again.
Sorry if I double bug but I didn't find any similar problem with this.
Sorry about my bad English...
Which cpu frequency driver are you using, acpi_cpufreq or intel_pstate? Thanks.
I use acpi_cpufreq driver, I think. In my previous attachments there is output of lsmod command.
Please try the intel_pstate driver which is normally recommended.
Thank you for advice. I didn't upgrade my kernel for a long time and I didn't know about this module. Now I have 3.9.3 kernel with set intel_pstate and I see the difference of scaling my processor. It is more flexible.
If it doesn't solve my problem, I will write about this (I hope so not). Now I have to observe this for a while...
I think that one week is enough and I can say that intel_pstate is module which solves my problem. Once, when I woke my laptop, the power button started blink, but of course this is another problem and I heard that this is popular bug in mainline 3.9.
I have a one question. Which processor family I should use: 'Generic-x86-64' or 'Core 2' to this laptop? I have i3-2310M processor.
Thanks a lot!
Ok. So close this bug since intel_pstate driver work normally.
From my opinion, it should be Generic-x86-64.
