I cannot do *anything* at all though. I can't reboot by holding down the power; I cannot exit the menu or even move the selection highlight to try and move to exit or continue. It's completely, totally, absolutely stuck on the USBnet menu with the options:
E) 511 with device into
Z) Enable USBnet
M Mount nfs
S Stress Tests

X) Exit - FW RIGHT to exit
It's also Tequila v.1.0.6.194
