Comment 4 for bug 1887218

A test kernel, based on UBUNTU: Ubuntu-5.4.0-42.46, is available @ https://people.canonical.com/~alexhung/LP1887218/ver1/

If this solves this bug, we can keep bisecting. If not, we can try other patches.

The following commits are excluded:

We can come back to these if the test kernel fails.

This requires additional patch(es) but this is to replace an existing function with acpi_dev_hid_uid_match and should not have any effects
