external USB drive hangs and unable to recover without hard reset

I'm experiencing this with all 5.x kernels usually within a day or 2 of a restart:
Jun 29 20:20:35 tiny-myth kernel: [85834.433030] xhci_hcd 0000:04:00.0: WARN Cannot submit Set TR Deq Ptr

I've rolled back to 4.19 kernel and error did occur once but appears to happen less frequently (running for a few days now and hasn't triggered).

This is on a device that's been running fine since 2012 with none of these issues until I upgraded to 20.04 in January 2021, at which point I've had to reboot the device constantly to re-attach to storage.
