I wasn't looking at the printk, I was looking at those 64-bit types. My argument was that while the small size is incorrect, it shouldn't cause system stability issues per se - it should just cause IO to potentially "wrap around" and go to the wrong place on disk.
Which is very serious in itself, of course - but what surprised me was the quoted system stability things.
Anyway, that patch only matters for the LINEAR MD module, and only for 2TB+ aggregate disks at that, so it doesn't explain any of the other problematic behaviour. Something else is up.
