parport and parport_pc not loading...

crimson · /usr/src/linux-2.4.19-gentoo-r10/drivers/parport/

I compiled parport and parport_pc as modules, and I get this message when I try to load them:

The output of the above command was:

/lib/modules/2.4.19-gentoo-r10/kernel/drivers/parport
/lib/modules/2.4.19-gentoo-r10/kernel/drivers/parport/parport.o
/lib/modules/2.4.19-gentoo-r10/kernel/drivers/parport/parport_pc.o

Ok, I did a make menuconfig and realized that they were built into the kernel.
I decided to try making them modules, then ran make modules and make modules_install. modprobe parport loaded fine, but modprobe parport_pc gave the following error :

ok, I'll do that, but

.. will they work?

and is there any special way to put them in the modules.autoload?

(ie alias, etc)?

well printing still doesn't work. I *can get the parport module to load, but NOT the parport_pc module.

My printer's stats in the bios are io: 378h / irq : 7 .

I try loading parport_pc with:

just checking, after compiling the kernel, did you put the new bzImage file in /boot and reboot?

cp /boot/bzImage /boot/bzImage.old
cp /usr/src/linux/arch/i386/boot/bzImage /boot

yes, I have these modules compiled and all support for parport and lp in the kernel. And I made sure to reboot with the *new kernel.

I am thinking about installing redhat 7.3 on a different hard drive and seeing how they handle it. I'm also going to try and change the irq for my parallel port in the bios.

could you try to just use the io address, but no irq:

I still get the same Device or Resource busy error as above.

dmesg | grep parport tells me :

parport0: PC-style at 0x278 (0x678) [PCSPP(,...)]
parport0: irq 5 detected
lp0: using parport0 (polling).

(replace irq 5 with 7, and 0x278 with 0x378 before I switched them in the bios. Exactly the same output as before though)

parport loads fine, but parport_pc is what gives me the error : Device or Resource busy. With either IRQ(5/7) I get the same error.

lsmod gives

Ok, I did cat /proc/interrupts when I had my parallel port as irq 5 and got:

2: 0 XT-PIC cascade

Then again with my parallel port as irq7:

sorry, I'm not quite sure how to change irq's for my sound card. The bios only has option to change the parallel port and serial ports.

OK, this is good news for once :). I updated the kernel, and built parport and printer support into the kernel. It looks like the kernel finally detects my Printer!

Here's my dmesg output:

parport0: PC-style at 0x378 (0x778) [PCSPP,TRISTATE,EPP]
parport0: irq 7 detected
parport0: faking semi-colon
parport0: Printer, HEWLETT-PACKARD DESKJET 710C
spurious 8259A interrupt: IRQ7.

pty: 256 Unix98 ptys configured
Serial driver version 5.05c (2001-07-08) with MANY_PORTS SHARE_IRQ SERIAL_PCI ISAPNP enabled
ttyS00 at 0x03f8 (irq = 4) is a 16550A
ttyS01 at 0x02f8 (irq = 3) is a 16550A

lp0: using parport0 (polling).
lp0: console ready
ppdev: user-space parallel port driver

However I still can't print :(. Any suggestions?

I got it to WORK!!! Ok, the problem was that I figured since I couldn't (and still can't) do a echo "printer test" > /dev/lp0 that the device wouldn't print. This is wrong!

I set up foomatic and cups with this command:
foomatic-configure -s cups -p 71232 -c /dev/lp0 -n Deskjet -d pnm2ppa

And much to my surprise a test page actually printed out! The other problem I had was not having PARPORT_PC_SUPERIO=y in the kernel.

Thanks for trying to help me out, it took a long time!
