Hi, please check if the tx queue gets stuck. If rt2x00 is built with
debugfs you can find a file names "queues"
in the driver debugfs dir.

So, the TX queue is indeed stuck :-(
Do you have a high IRQ load on the system?
Do you have a serial console attached?

This only happened on HIGH wifi load and can stand for week while idle. For
example when I come home and download a torrent with 10-15MiB/s with a wifi
it lose all I/O with dmesg errors described above. But router is fully
operable, has ethernet cables connected and provide full features to the
local lan and working internet for all who is on ethernet.
To reenable wifi back I have to run (without need in router reboot):
rmmod rt2800pci
insmod rt2800pci
wifi down
wifi
I do not have console, but I have ethernet so I can run everyting.
