[Kernel-packages] [Bug 1506050] Re: intel cpu frequency is stuck at ~400mhz

2016-03-31 Thread Chris Ng
According to that bug report, thi was fixed in thermald 1.4.3-5~14.04.2.
I have that installed, and microcode 0x36 and frequency scaling appears
to be working correctly.

Title:
  intel cpu frequency is stuck at ~400mhz

Status in linux-lts-vivid package in Ubuntu:
  Invalid

Bug description:
  I upgraded an install of 14.0.4.3 to the LST Enablement Stack for
  Vivid (kernel 3.19) that is running on a Xeon E5-1630 V3 (a Haswell
  Quad-Core) .  Booting with 3.19 would result in the system being very
  sluggish.  'cpupower frequency-info' would report that the CPU was
  running at around 400mhz, as would 'cat
  /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq'.  The CPUs
  would remain around 400mhz regardless of load.

  This was using the intel_pstate driver and the powersave governor.
  Switching to the performance governor had no effect.  Using the acpi-
  cpufreq driver also had no effect, the system was still sluggish even
  though the reported frequencies in /sys/devices/.

  Eventually I tracked it down to the original install having had the
  intel_microcode package installed at some point.  Once I removed this
  then the CPU frequencies scaled correctly with load.  FYI the
  particular version installed was intel-microcode/trusty-updates,now
  2.20140624-t-1ubuntu2 amd64.

I won't have access to the machine for about a week, I will try and test
the new package then.

[Kernel-packages] [Bug 1506050] Re: intel cpu frequency is stuck at ~400mhz

2015-10-27 Thread Chris Ng
Turns out that this was because I had a 'new' version of the intel
microcode that I must have downloaded from Intel itself in /lib/firmware
/intel-ucode when trying to diagnose a VM lockup a year or so ago.  It
updated my Haswell to 0x29, whether it's the upgrading of the microcode
or the 0x29 microcode itself causing the problem I'm not sure.

Using the 'vanilla' intel-microcode package without any modifications
seems to work fine.
