Title: lenovo x260: unable to suspend or power off cleanly Status in linux package in Ubuntu: Confirmed Bug description: Since upgrading to the new 5.15 kernel in Jammy development I've been unable to suspend or power of my x260 successfully. suspend - laptop appears to have suspended with the power led pulsing but then won't resume power off - laptop appears to have powered off but infact has not - power led is off - have to hold down power button to 5s to fully power off. I was convinced this was a hardware issue so tried with a 20.04 live image which completed both operations sucessfully. I've tried all 5.15 kernels including the one in jammy-proposed.
