Description Flags
dmesg output with call trace for 737 kernel none

Description Andre Robatino 2005-01-15 17:56:16 UTC 
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:

  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).
