[Kernel-packages] [Bug 1506050] Re: intel cpu frequency is stuck at ~400mhz
Chris Ng, FWIW, there is a big chance that the issue you observed is ultimately caused by thermald depending on weakly specified behavior that is known to be processor-model-specific, and which we now know to be also microcode-level specific. Please refer to bug #1480349, and remove thermald from your system. Don't run thermald on any Xeon boxes. Removing thermald has a good chance of fixing the issue you observed, as the modified Ubuntu version that detects and refuses to run on Xeon boxes had not yet been sucessfully backported to vivid-lts at the time I wrote this reply. A reboot is required after removing thermald, to ensure all processor MSRs are reset to firmware/kernel defaults. If you do test the new microcode with thermald removed, please drop us a note on this bug report.Other users find this bug report through Google, and the information would be helpful to them. If removing thermald does NOT fix your issue, I would really like to know about it to further try to debug this issue. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lts-vivid in Ubuntu. https://bugs.launchpad.net/bugs/1506050 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) .

[Kernel-packages] [Bug 1506050] Re: intel cpu frequency is stuck at ~400mhz
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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lts-vivid in Ubuntu. https://bugs.launchpad.net/bugs/1506050 Title: intel cpu frequency is stuck at ~400mhz Status in linux-lts-vivid package in Ubuntu: New 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) .

[Kernel-packages] [Bug 1506050] Re: intel cpu frequency is stuck at ~400mhz
Henrique de Moraes Holschuh, to advise, it's not a guarantee that a newer microcode will ever be imported into Ubuntu, let alone import a newer one that has a potential/confirmed regression. What is expected during a consideration phase is a regression testing regime. However, if one has a concern regarding a version of the upstream firmware potentially being backported into Ubuntu, then one would want to contact the Ubuntu maintainers of the firmware directly via relevant mailing list (not via a bug report). Issues in the version of firmware in an upstream repository (not downstream in Ubuntu) is not something to open a bug report about here in Launchpad, nor toggle open an already closed report. Instead, one would want to pursue this with upstream directly. Hence, toggling the status of this report further, or making Chris Ng perform further testing is unnecessary, and the wrong venue.

[Kernel-packages] [Bug 1506050] Re: intel cpu frequency is stuck at ~400mhz
This bug report should NOT be closed without direct verification by the submitter. The new microcode update distribution DOES contain microcode with a revision of 0x29 or later for the Xeon 1200v3. This means it *CAN* cause the regression reported in this bug report. And the microcode update packages *are* backported to older releases. Therefore, one should *never* close bug reports related to regressions caused by *NEWER* microcode updates -- they will eventually land everywhere (through a bios update, through backports, etc). The only safe ones to close are those related to *outdated* microcode. Please keep this bug open until you get a confirmation from Chris Ng that the latest microcode update (20151106) did NOT cause the same regression. ** Changed in: linux-lts-vivid (Ubuntu) Status: Invalid => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lts-vivid in Ubuntu. https://bugs.launchpad.net/bugs/1506050 Title: intel cpu frequency is stuck at ~400mhz Status in linux-lts-vivid package in Ubuntu: Confirmed 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) .
