So it seems you're getting stuck in here. Not knowing the code or what
could be broken that you're getting stuck crazy an idea would
it be to insert some kind of jiffy counter in such potentially "infinite
loops" to abort the loop after "too much" time has been spent waiting for
some condition that's apparently never going to happen?

Maybe even put in a printk to make noise about having to abort the the problem isn't totally swept under the rug, but systems don't
lockup either.
