Until we have a better solution, are there any strategies we could
apply here to avoid the suspend as you say?
e.g. DMI quirk these products to disable suspend? Or disable suspend
on all s2idle setups?

This would certainly be better than the current situation of the
machine becoming unusable on resume.

Thanks for following up on this internally! Can I lend a product
sample to the new team so that they have direct access?
