Hi, I'm sorry for the late reply. After rebooting my computer was not functioning any longer :). Yes, I have a USB 3.0 controller and an external disk attached to it in a x86_64 system. Once I unplugged the disk everything worked as should be and I manage to install the new kernel. I have notice that trying to downgrade to previous linux version lead (3.0.2) lead me to the same problem despite I could install it without any problem when it was pushed. I haven't tried to plug it back and I won't be able to until monday. Any body knows what happened? Hector PD: Thomas Bächler: I will try to reproduce the problem on Monday and I will post you the output of 'ps fx'.
