Unfortunately, I can't. For some weird trick of fate, I typed `rm -rfv /usr/lib` on my UBUNTU 15.04 and should I say what happened? I had to reinstall my whole environment, and since I was getting all kinds of glitches (HDD, all of the sudden it gave up with S.M.A.R.T. errors forcing me to buy another one, WIRELESS B43 driver was restarting my system even before the Intel_power_clamp started screaming, the SYSTEMD wasn't starting the OpenVSwitch in correct boot order, so I couldn't start my firewall VM automatically), well, I decided to give another distro a try, and guess what? No problems at all... With the intel_power_clamp running on kernel 4.0, so far, so good, and for whatever reason it was locking my system it appears to be only affecting UBUNTU 15.04. Right now I am using Linux MINT 17.1 which is a distro based on UBUNTU 14.04, perhaps in a future time I may have to call you back, but until then I hope you have sorted what is breaking my system. If there is anything I can do to help you with this 'older' version that I can try, please ask me, but no promises on finding the glitch since I won't go into UBUNTU 15.04 so soon again, after all this machine is my only network server. Anyway, thanks for your time and help, and I hope you can find that pesky bug. Thankful, Gustavo
