No, I think Guenter is saying that current mainline *without* the
patches works fine.

But v6.1-rc2 (which is quite close to that current mainline) *with*
the patches blows up.

So it's almost certainly the patches that break. There are no
appreciable timer changes in those 105 commits (there's some added
irq_work_sync but that looks very unlikely to be related.
