I'm on Ubuntu 11.10 and using Core i7 2670QM. Suddenly from today this kind of issue has started. But it's little different.
Sometimes it shows 8 cores and sometimes just 1. I don't need to reboot the system. this happens at random interval. The system is updated till date. (Updated in the afternoon to be specific and seen this issue since evening). What logs should I attach? -- 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.
