I've seen these indefinite IRQ waits too. I noticed at least that they aren't all happening from any one specific transceiver state. At one point I was unintentionally getting close to having a repeatable test to reproduce it, but in normal use I only see it very rarely. I will look for a solution next time it starts happening more.

However, I don't think it's bad enough to block the PR. I am finding this reliable enough that I've stopped using a watchdog timer in desperation to find more crashes.

The discussion here is getting almost too long to read thoroughly, so I have to apologize for asking: is anything blocking this PR from proceeding now that it was decoupled from #7897?
