Most likely is not fixed. We have those new commits in 5.3:

41a531ffa4c5 rt2x00usb: fix rx queue hang
0f47aeeada2a rt2800: do not enable watchdog by default
e403fa31ed71 rt2x00: add restart hw
710e6cc1595e rt2800: do not nullify initialization vector data
09db3b000619 rt2800: add pre_reset_hw callback
759c5b599cf4 rt2800: initial watchdog implementation
2034afe4db4a rt2800: add helpers for reading dma done index
9f3e3323e996 rt2x00: allow to specify watchdog interval

Most suspicious are 710e6cc1595e and 41a531ffa4c5 .

Could you test by reverting one single commit on 5.3
(first 710e6cc1595e and if that not help 41a531ffa4c5)
and check if it makes the problem gone?
