Maybe it was some coincidence/whatever. Maybe it is some hardware issue of exact mask version. When I first started hacking around PXA, it was known that tosa sometimes does not reset the AC97 codec for the first time. However it looks like nobody bothered to debug that, because in most (~3/4) cases reset went through. Now some kernel changes made kernel hang looping in the interrupt, if the reset is not properly handled.
Ah, now you mention that extra detail I do recall Wolfson CODEC drivers with suspicious extra resets - probably this issue was why.
