I can reproduce with following steps: 1. do factory recovery (Xenial oem install) 2. upgrade linux-firmware along to 1.157.22 3. completely power off and reboot after 1 minute 4. trigger system suspend
In the beginning CAP lock indicator is blinking, and then keyboard may have one flash, then power LID always on and leaves the system hard lockup state. No response to kernel magic keys or power button (short) presses. ** Package changed: linux-oem-osp1 (Ubuntu) => linux-firmware (Ubuntu) ** Changed in: linux-firmware (Ubuntu) Status: New => In Progress ** Changed in: linux-firmware (Ubuntu) Assignee: (unassigned) => You-Sheng Yang (vicamo) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1857883 Title: system failed to suspend To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1857883/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
