SRU Request: When running the 'stress' stress testing tool a Lenovo Edge 11 locks up because of CPU overheating. This is fixed using upstream patch "cpuidle: menu: fixed wrapping timers at 4.294 seconds" (merge commit f310642123e0d32d919c60ca3fab5acd130c4ba3 and 2.38.y stable commit 4a1163dff6592dcee594b2bee597aafd749b93ee).
This fixes errors in predicted sleep times which selected incorrect C states, causing increased power consumption and on some machines overheating and critical thermal shutdown. The bug also broke cpuidle state residency statistics which made it hard to spot this bug. With this fix, the Lenovo runs the stress test without locking up. Also this fix reduces overall power consumption and hence longer battery life. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/774947 Title: [Lenovo Edge 11 AMD] system locks up completely running the "stress" tool To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/774947/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
