Description of problem: Parallel port printing is broken by the 737 and 741 kernels. There is a call trace during bootup indicating that the kernel can't find the printer. Print jobs are queued but not printed. Adding the two lines alias parport_lowlevel parport_pc options parport_pc io=0x378,0x278 irq=7,auto to /etc/modprobe.conf gets rid of the call trace and the printer will then work. Below I attach the dmesg output for the 737 kernel (the problem with 741 is similar). Version-Release number of selected component (if applicable): kernel-2.6.10-1.737_FC3 kernel-2.6.10-1.741_FC3 How reproducible: always Steps to Reproduce: 1. Boot up in 737 or 741 with a parallel port printer connected. Actual results: Call trace during bootup. Printing doesn't work. Expected results: No call trace. Printing should work. Additional info: Fix comes from Fedora Forum: http://www.fedoraforum.org/forum/showthread.php?t=31844

I forgot to mention that this happens to my father with a 6-year old Emachine, but not to me with a Microtel SYSMAR561, even though our printers are identical (and both connected to /dev/lp0).
