Public bug reported: Problem description: System randomly hangs during suspend when mei_wdt is loaded.
Platform: Intel Dawson Canyon I5 (NUC7i5DNHE) and I7 (NUC7i7DNHE) Test procedure: 1. Install Ubuntu 18.04 and do apt full-upgrade 2. Enable mei_wdt: $ sudo modprobe mei_wdt 3. Do system S3 test: $ sudo systemctl suspend or $ sudo rtcwake -v -m mem -s 15 4. Afterward, I noticed that somehow system will hang during suspend/resume. Expect result: Suspend/resume won't impact system. Actual result: System will hang during S3 test. Additional info: - BIOS version: V57 - Another i3 platform (NUC7i3DNHNC) doesn't have this issue. ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1803942 Title: System randomly hangs during suspend when mei_wdt is loaded To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1803942/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
