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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lts-vivid in Ub

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

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 pack

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

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 micr
