2.1.10[56] parallel port problems

Am I the only one having problems with the parallel port behaviour in
recent kernels ?

In 2.1.105 and .106, printing is essentially broken for me. It seems
as if "flow control" does not work - the print-outs I get have missing
lines, garbled data and look just plain awful. Oddly, there seems to
be no errors, warnings or other messages logged anywhere - as far as
Linux and lpd are concerned, everything looks fine and dandy.

Rebooting 2.0.33 makes the problems go away.

The printer is an Epson Color Stylus II.

The parport driver is completely modular, with options

alias char-major-6 lp
alias parport_lowlevel parport_pc
options parport_pc io=0x378

Log messages when the module loads:
parport0: PC-style at 0x378 [SPP,PS2,EPP]
parport0: no IEEE-1284 device present.
lp0: using parport0 (polling).

(the printer wasn't turned on when the modules loaded; when it is, it
correctly detects my printer).
