Seems like my old faithful is starting to go bad somehow.
When I first turn it on I have a lot of problems with freezes. Sometimes they unfreeze after a while, sometimes they don't. One thing I notice is that miami says it can't open ariadne_ii.device unit 0 and I have to turn it off to fix that, not just reset.
Though, after about 20 minutes of this everything seems to work normally again with no freezes or similar errors. This tells me it's somehow temperature related.
Question is, is it the zorro daughter board, the ariadne or the CS Mk II. Gonna open it up and re-attach everything to see if it helps. After starting to play with my A4k again last week it hadn't been on for about a year.
