This is still a problem as of today on a Dell XPS 15z,Intel(R) Core(TM) i7-2640M , Ubuntu 11.10 with kernel 3.0.0-14-generic.
Htop, gnome-system-monitor, top all report one core when in fact there should be 4. What logs should I attach? I see Muneeb has been ignored. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/823634 Title: Core i7 2630QM sometimes recognized with only one core.
