Most probably, you ran into a known kernel bug: when the parport is set 
to ECP mode, the kernel thinks it also support EPP mode. When the driver 
tries that mode, it gets stuck. The solution is to set your parport to 
EPP mode in the BIOS (EPP+ECP may work too, but I've also had problem 
reports with that combination).
