I think the issue is that at some point HW/FW is not capable to sent frames and do not report to driver failure of sending frames, hence driver queue can not be moved forward. The solution to this will be timeout mechanism for TX, similar like for rt2800usb, however this will require substantial rt2800pci/mmio driver rewrite. I'm going to look at this, but not sure when.
