I have disabled parport from my latest kernel build as I do not require Parallel ports. This leaves warning messages about failing to install ppdev, parport_pc, and lp (options related).
How do I remove whatever is still activating the warning messages? (not the messages themselves, Don’t want to lose kernel log level)
sleekmason
Root of the matter: Why am I getting info on boot about drivers failing if I have removed/unchecked the corresponding drivers in the kernel .config file using make menuconfig. Shouldn’t unchecking these drivers also remove any info printed?
sleekmason
Narrowing it down further: Why is modprobe trying to load drivers that no longer are present in the kernel? and, how to get it to stop. Adding a file blacklist.conf to /etc/modprobe.d, and listing as “blacklist ModuleName” didnt have any affect. The file is being read – checked with another command.
ohh
It appears that the other modules depend on paraport, e.g., ppdev, parport_pc, and lp. If you don’t need them then you will need to either remove them in the kernel, or remove them via:
module -r

Thank you for responding.

The whole group was disabled. Parport is the parallel port driver, and the other three have functions related.
–
The error message is saying that modprobe is searching for the drivers in /lib/modules/(my-current-kernel-version), and there is also a human readable copy of the list of modules to be activated/installed on boot named modules.dep in the same folder.
None of the 4 modules exist in /modules.dep, – (parport_pc, ppdev, lp, and parport).
My understanding is that modprobe reads from the list created there, and therefore shouldn’t be throwing messages. I also should note that I updated initramfs again just in case.sleekmason
I should say that this is by no means a huge deal and is a pretty obscure question to ask. Not exactly distro related. I have options like changing log levels or simply putting them back into the kernel. This is a furthering my education question. Seems like it might come in handy someday.

Have you checked to make sure they are not listed in /etc/modules ?
I believe lp gets added there during installation, possibly its dependencies also.sleekmason
Yes, Nothing listed in /etc/modules but loop. Could udev be finding the hardware and expects modprobe to find the drivers?
wildstar84
Why not just blacklist them by creating a text file in /etc/modprobe.d/, say “my_blacklist” with the lines:
blacklist parport_pc
blacklist ppdev
#etc…Regards,
Jim

Why not just blacklist them by creating a text file in /etc/modprobe.d
–
could, but the point is to remove the option entirely from the kernel without dealing with the messages. There is no significant benefit to disabling them. I wouldn’t advise anyone to bother. The point is to learn more about the system and how it works.
–
Something, I’m guessing eudev/udev is showing the port and expecting drivers to be loaded. Shouldn’t eudev have a way to turn off those options?I’m guessing not at this point but don’t really know.
The answer could be obvious in that modprobe.d (and associated) are what is being used for user interface, and no human usable file exists before then. If there was something further up the line (other than bios), we would be using that to set instructions for driver install instead.
–
This is me guessing . . a lot.sleekmason
Did a little digging. This is probably what I am looking for.

How to functionally edit a file in dev using the major/minor number for the driver is beyond my skill set. I don’t reckon I need to go any further if this is it. Just not worth the trouble, unless I’m missing something.CONFIG_DEVTMPFS: │
│ │
│ This creates a tmpfs/ramfs filesystem instance early at bootup. │
│ In this filesystem, the kernel driver core maintains device │
│ nodes with their default names and permissions for all │
│ registered devices with an assigned major/minor number. │
│ Userspace can modify the filesystem content as needed, add │
│ symlinks, and apply needed permissions. │
│ It provides a fully functional /dev directory, where usually │
│ udev runs on top, managing permissions and adding meaningful │
│ symlinks. │
│ In very limited environments, it may provide a sufficient │
│ functional /dev without any further help. It also allows simple │
│ rescue systems, and reliably handles dynamic major/minor numbers.ohh
sleekmason,
That’s very interesting, don’t think I’d personally try it on my main box.
Definitely beyond my skill level.cheers,

howdy ohh!

I’ll probably mess with it again sometime but agree I don’t want to have reinstall anytime soon.
–
Already lost udev in smxi yesterday piddling around. Did the cruft removal where it says “one by one” – Took that to mean “verify before each one” as there was already an option for “all”. I then watched it indeed remove the packages one by one all in a row. geez. There goes udev.
–
Anyway, my laptop would still boot to fluxbox, but no mouse or keys, so I wound up attaching a cable from my router to get internet, booted into init 3, ran Ceni, installed udev, rebooted into fluxbox, then dist-upgraded using “dev” at the end of the repo line. Yikes!ohh
Howdy sleekmason,
I try to keep my desktop stable, it is an older iMac 2006, but I do play around on my laptops as it is dead simple to reinstall if I foobar them!!
Which does occasionally occur.
But an education always requires payment of some kind.cheers,

hello
Had you modded the kernel in use?
If yes, what were your objectives?
If to optimize an old hardware, please provide main lines/directives, or you don’t have time, maybe a web tutorial suggestion.
After default way upgrade, the system is 4.10.5-antix.3-amd64-smp . Have you notice any slow down? This netbook is Atom N450 dated Q1’10 with 2 GB [seems like there is a flat out uninvited mining daemon]
off-topic: JFS, instead of ext4?
