"To turn off the 'protocol in hardware' code paths, disable
CONFIG_PARPORT_PC_FIFO. Note that when they are enabled they are not
necessarily _used_; it depends on whether the hardware is available,
enabled by the BIOS, and detected by the driver."
is no longer working anymore - with 2.6.7 it worked as described. The parport was set in polling mode and the printer printed alright.
After the update to 2.6.10 the parport is always interrupt-driven and the print jobs end up in nirvana.

HowTo avoid this? Bug or Feature=
