--- Comment #12 from Ferry Toth (ferry.toth@elsinga.info) ---
Ah, ok I was looking at a stack trace from a more recent kernel. So, here to
add some more data points (2 different kernels):

This is with EVB LAN9514 plugged in while booting:

This is after boot, plugging the EVM-USB2517, then plugging a mouse:
