Finn,
... Multiplatform interrupt support might be another one.Yes. My hunch is that this issue is interrupt related.Were there interrupt changes on the atari side between mainline 3.10 and3.12 (?)
Not on my part - I still haven't gotten around to switching to 3 12 yet. The generic hardirq changes Thomas Gleixner worked on were out of tree, right Geert?
Serial or early fb console looks the only way to debug this. Cheers, Michael
