Thanks for the confirmation. I went ahead and submitted a patch for the
suspected SRNG restart issue in [5].

For my P14s Gen 5 AMD, I don't think the PM quirk is the right fix at
this point, so please don't include the 21ME/21MF IDs on my account for
now. This new patch seems like a better match for the disassociation
issue I was seeing after resume.

Please try it out if you have a chance. I've done around 12 sleep/wake
cycles so far without issue.
