[Skiboot] The state of "Running pollers with lock held"

[Stewart Smith]

So,

I merged my patch to rework fsp_fetch_data to support proper
asynchronous fetching. This gets rid of the major source of these
warnings.

We may still have something in an op_display() code path (I should
really save the backtrace next time I see it).

We also have:

as well as (when doing code update):

Anyone want to volunteer for fixing these?
