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.

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.
