I have the same problem on Acer Aspire 5750 (Intel Core i5 2410M / Intel HD Graphics 3000). No sings of overworking, every month for me (maybe equivalent to 24-48 hours). The system version is 12.04.2 LTS and I tried normal 3.2 kernel and 3.5 Quantal HWE kernel; the same happened with both of them.
Interestingly, hard freeze used to be happening on another Acer Aspire V3 (Intel Core i5 3210M / Intel HD Graphics 4000), too, and after upgrading it to 12.10, this trouble disappeared (at least for a number of months). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1159065 Title: kernel hard freezes unless processor.max_cstates=1 is used To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1159065/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
