Having just installed FreeBSD 4.0, when I do printing, I get
error messages like:
stray irq 7
It prints fine, so it doesn't hurt me in any way, but I thought
you should know.
These are the lines in my kernel configeration file for the printer:
# Parallel port
device ppc0 at isa? irq 7
device ppbus # Parallel port bus (required)
device lpt # Printer
#device plip # TCP/IP over parallel
#device ppi # Parallel port interface device
#device vpo # Requires scbus and da
Here is the complete dmesg - maybe it will help you.
