Well, I cannot finish printing anything now and I believe, that one of
above is responsible.
It looks as if printer gets some amount of data but then communication
'stops' and printer waits for more data (usually I have about 2cm
of page printed, paper locked and later printer error leds start
blinking happily :)

Not sure, if it's directly related, but system seems to be less
responsive later.

Version of usblp.c from 2.6.0-test2 compiled with 2.6.0-test3 does
not work as I expected (I can load module, but printer is not
detected - no usual 'usblp0: USB Unidirectional printer dev 3 if 0 alt 1
proto 2 vid 0x03F0 pid' message in logs).

I traced my problem down to -test2-bk2 (with bk1 everything works
correctly).

o Printer is connected to /dev/usb/lp0; it's HP840c
o ver_linux output: http://zeus.polsl.gliwice.pl/kernel/2.6.0-test3/ver_linux
o config: http://zeus.polsl.gliwice.pl/kernel/2.6.0-test3/config
o dmesg: http://zeus.polsl.gliwice.pl/kernel/2.6.0-test3/dmesg
o /proc/bus/usb/devices: http://zeus.polsl.gliwice.pl/kernel/2.6.0-test3/devices
o some related logs: http://zeus.polsl.gliwice.pl/kernel/2.6.0-test3/logs

Any suggestions are welcome :)
