In case of Lenovo X1 Extreme Gen 5, the issue seems to be with the latest BIOS.
BIOS version 1.20 (N3JUJ13W) is causing the Elan TrackPoint device to stop
working after wakeup from S3.
Rolling back to 1.19 (N3JUJ13W) solves the issue.

Is there any kernel debug flag that I can set to help debug this
further?

the BIOS update.

I think 48W is the suffix of the BIOS version, N3BET48W.
The new BIOS 1.25 released Aug 9 seems to contain 47W, and indeed does
