For example, the _CRT (critical trip point) for GFXZ tries to index into \_TZ.TRIP in the GETP() method and ARG0 in this call references element 6 in a 2 element package, which results in a failure. So I guess a bunch of critical trip points are all invalid, which may mean your CPU is scaled down to the lowest speed. What does the following output? for I in /sys/class/thermal/thermal_zone* ; do echo $I:; cat $I/trip_point* ; done -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1253734 Title: scaling_max_freq is less than highest frequencies in scaling_available_frequencies Status in “linux” package in Ubuntu: In Progress Bug description: brendand@brendand-6930p:/sys/devices/system/cpu/cpu0/cpufreq$ cat scaling_max_freq 1520400 brendand@brendand-6930p:/sys/devices/system/cpu/cpu0/cpufreq$ cat scaling_available_frequencies 2534000 2533000 1600000 800000 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1253734/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
