Subject: 2.6.9-rc3 and rc4: parallel printer has gone

After upgrading kernel 2.6.7 to 2.6.9-rc3 my parallel printer can't be found
anymore. Same situation with rc4. The .config file is the same as for 2.6.7.
Starting kernel 2.6.7 makes printer available again. Printer is a Brother HL
1430, which never made troubles before. Bios is set to ECP/EPP.

With kernel 2.6.9-rc4-mm1 the parallel printer is visible again.

The parallel printer disappears from 2.6.9-rc2 to rc4.

lp: driver loaded but no devices found

The rc-1 and rc4-mm1 versions are ok.

It looks like the patch from Olaf Hering <[email protected]>
http://www.ussg.iu.edu/hypermail/linux/kernel/0408.0/0792.html
causes the problem.

A patch from Andrea Arcangeli <[email protected]>
http://www.ussg.iu.edu/hypermail/linux/kernel/0409.3/1515.html
corrects the problem.

It looks like the Linus tree only has Olaf's patch.
Andrew's tree (mm) has Andrea's patch.
