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.

Worked around for now by disabling the security chip via the BIOS.

Same problem occurred by upgrade (from 21.10 to 22.04) on my x260 model 20F5S3BR00.
Can confirm workaround working by disabling "security chip" in the BIOS.
