 Posted: Sun Oct 17, 2004 10:35 am Post subject: parallel printer has gone (kernel 2.6.9-rc3 and rc4) |
 |
|
After a kernel upgrade from 2.6.7 to 2.6.9-r3 my parallel printer (Brother HL 1430) has disappeared. Same thing with rc4. Starting 2.6.7 makes printer available again. The .config file is the same on all three kernels. The printer never made any problems before.

piewie,
How do you mean | Quote: | | The .config file is the same on all three kernels |
You must at least run when you move a config file from one kernel to another.
That prompts you to answer the new questions and ensures you have a valid config for the kernel you want to build.

After make oldconfig resulted in the printer problems, then compiling parport in the kernel, then compiling parport as modul again I used the "Load an Alternate Configuration File" - Option (which has never been a problem). But all with no success.

I also found out that my parallel printer vanished, don't know when, because I do not print very often.
I then got the idea that I might lack the /dev/lp0 and I was right.
So I wrote
lp
parport
parport_pc
in my /etc/modules.autoload.d/kernel-2.6 and now it works, allthough I do not know,
why once the modules are loaded and create the neccessary nodes in /dev without theses entries.
Maybe this helps  |

I already have the necessarry entry for the modules. The printer worked perfectly for the last 20 compiled kernels (2.6.0-betaxy - 2.6.7-mm4).
Then I changed to 2.6.9-rc3 and the problems began.

You need to: 'modprobe lp' if you didn't already do it.
Did you do make modules_install and the rest?
Double check: http://www.gentoo.org/doc/en/printing-howto.xml .
Does 'cat test.txt > /dev/lp0' work?
Error messages when loading module?

Yesterday my trials resulted in:
dmesg | grep lp0
lp: driver loaded but no devices found
cat log.txt > /dev/lp0
bash: /dev/lp0: No such device or address
But /dev/lp0 is there. I made it with mknode 6 c 0

That's odd. The lp0 is the key to the problem.
In device drivers - character devices do you have parallel printer support enabled? I missed that one once. Otherwise it's just to check:
Parallel port support
PC-style hardware
Multi-IO cards
Support for foreign hardware
IEEE 1284 transfer mode

Modules are autoloaded. The configuration is the same as many times before, where the printer was working.

It could be a bug since you're going with a beelding edge kernel. For me I usually missed something. lsmod and dmesg helps. But if the lp module can't find the device I would check the cables/power first of all. I don't know why but something tells me this should be picked up in BIOS first of all (check there too). After that I would even copy/move the config and do a make clean and see if I that helps.
I hope you figure it out, I got to go to a theatre now. Good Luck!

Printer is back again with kernel 2.6.9-rc4-mm1 with same configuration file as before, but still not useable.

I couldn't. But now I can: it seems that there is also a bug in kde 3.3. The configuration with Printing Manager results in a printer, that cannot print test pages.
Using foomatic-configure results in a perl error message, but the printer is useable and can print test pages.
I try to find the kernel versions, that work correctly. Perhaps You can do so to. I made a bug report in the kernel mailing list. They want to know, with which kernel version the problem began and when it ends.

Ok, affected kernels are 2.6.9-rc2, rc-3 and rc-4,
kernel versions with correct parallel printer implementation are 2.6.9-rc1 and 2.6.9-rc4-mm1 (self tested)
And I heard that 2.6.9 final also can't find the parallel printer.

I had the same problem now it works with the following.
<M> Parallel port support
<M> PC-style hardware
<M> Multi-IO cards (parallel and serial)
[ ] Use FIFO/DMA if available (EXPERIMENTAL)
[ ] SuperIO chipset support (EXPERIMENTAL)
[ ] Support foreign hardware
[*] IEEE 1284 transfer modes
-- Character devices
<M> Parallel printer support
