Started noticing somewhere in the 5.9 devel cycle that removing a usb wireless adapter driven by the mt7601u driver, that removing the device after using it leads to a panic 100% of the time. With earlier kernels, I believe it didn't panic, though I did get a slew of Warning messages about TX and RX DMA not stopping.
