https://bugzilla.novell.com/show_bug.cgi?id=853140 https://bugzilla.novell.com/show_bug.cgi?id=853140#c3 --- Comment #3 from Borislav Petkov 2013-12-03 20:33:59 UTC --- Interesting. Can you do # grep . -r /sys/devices/system/cpu/cpu?/cpufreq/* as root and upload it? Also, we probably should rule out some cpufreq bug in 3.7 so can you check whether the upstream kernel here http://kernel.opensuse.org/packages/vanilla also doesn't have that scaling_cur_freq node on your machine? I think that should be all for now, thanks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=853140 https://bugzilla.novell.com/show_bug.cgi?id=853140#c7 --- Comment #7 from Borislav Petkov 2013-12-03 22:16:03 UTC --- So do you see it? You have scaling_cur_freq only when acpi-cpufreq is your driver and not in the case of intel_pstate. I wonder why 3.12 decides to load intel_pstate on your machine... Once it is loaded, it probably does Pstate switching differently and doesn't have ->target() and ->target_index() methods and because of that, cpufreq doesn't generate a scaling_cur_freq sysfs node. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=853140 https://bugzilla.novell.com/show_bug.cgi?id=853140#c8 --- Comment #8 from Bruno Friedmann 2013-12-04 09:05:29 UTC --- I didn't pay attention that this stuff change. The only thing I've done on my laptop was to remove nvidia blob, and use nouveau and also kernel-standard on it. A few weeks ago, I've applied the last Bios update was proposing for my laptop Precision M4600 http://www.dell.com/support/drivers/ch/fr/chbsdt1/DriverDetails/Product/precision-m4600?driverId=G3WFG&osCode=ww1&fileId=3215298012&languageCode=fr&categoryId=BI With a changelog containing 1. Updated to the 1.5.33 version of the Intel PXE OROM. 2. Addressed Trusted Execution issue with CCTK on non-TPM configuration. 3. Addressed extenal USB keyboard LED abnormal issue. 4. Addressed UEFI OS fail boot with HDD password present issue. I don't have uefi, not tpm activated. I will also attach the actual dmesg, where intel_pstate is loaded. Did you need anything else, or have a way to fix it ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=853140 https://bugzilla.novell.com/show_bug.cgi?id=853140#c10 --- Comment #10 from Borislav Petkov 2013-12-07 21:11:25 UTC --- Well, it looks like Intel wants this driver on Sandybridge, here's the Kconfig text about it: This driver provides a P state for Intel core processors. The driver implements an internal governor and will become the scaling driver and governor for Sandy bridge processors. When this driver is enabled it will become the perferred scaling driver for Sandy bridge processors. And your CPU is a SB, model 0x2a. Btw, I think you should be able to get the core frequency by running $ cpupower frequency-info even on that box.
