Hello to everyone, whenever I start Trisquel the Syslog and Kern.log files increase their size until I have to clear them otherwise I don't have enough free space to load the OS. How can I solve the problem?

Well, the good solution would be to solve the problem that must be repeatedly written in kern.log. What is it? Maybe it is a support issue that would be solved by the installation of a newer kernel: https://jxself.org/linux-libre/

I checked the files but I can't understand what they say. I installed the latest version of linux-libre kernel and sometimes I have to reboot the OS otherwise it doesn't work: everything is blocked. At the moment I can't understand what the log files contain, I'm not an expert....

When I started using my first computer, I also didn't understand how
things worked, over time, I begun understanding that I could only solve
my occasional computer problems if I do share what I currently have with
the people related to the same thing I use, even though I don't need to
understand everything that exists in the universe, because I'm not the
know-all-person. :)

Still as of today, when I have a problem I can't solve, or something I
can't understand, I seek advice from people who are related to those
things, and that I think that might have some experience to share. This
can be as simple as copying a little piece of text from that log file,
and inserting it here for us to read. So, go ahead and do as I just
said. ;)

Note, however that, if the text repeats over and over, or is too similar
to various ones, please paste only the first occurence.

Respectfully, Adonay.

Hi Davide,

You didn't say what kind of hardware you have, but I am 99 44/100% sure that the problem is a proprietary wireless card. I use Thinkpads and have to deal with this poo poo all.the.time.

They're great computers once you get it sorted out. Thinkpads have kind of a weird BIOS so you can't just replace the wireless card and you have to disable it.

If you can tell us a bit more about your computer and your experience and comfort level when it comes to replacing componants like wireless cards, we can help you figure out if you can just replace the card or if you need to disable it and use a USB dongle.

I am attaching a copy of my etc/network/interfaces file. Take a peek and compare it to yours. It is one of the files you need to add a few lines. The other is etc/rc.local, also attached.

Do save your original files as interfaces.old and rc.local.old before editing them unless you have a Thinkpad with factory BIOS (and maybe even then because hey, you might want to flash that factory BIOS and change it to something else someday) if you want to give this a try.

A libre internal wireless card is going to be under ten dollars and a USB dongle isn't much more.

Sorry I haven't been around until now. It's a very, very, very common problem and incredibly annoying and frustrating when you don't know what the problem is.

Those logs look normal. Do they still increase until you run out of disk space?

Davide, I have a bit more time today:

Here's the long version:

Having five lines (from "Missing Free firmware" to "Could not read microcode: -22") logged every 2ms (the numbers between squared brackets are times since the last boot) is abnormal... but the logs Davide0 attached are not like that. They look normal, hence my question: do they still increase until you run out of disk space? The newer version of Linux-libre may have solved the problem but the older logs may be still present, taking all the space. Let us see the output of the following command that shows the twenty largest files in /var/log:
$ ls -lhS /var/log/ | head -20
If you cannot log into a graphical session (a full root partition does that if I remember well), log into a terminal with Ctrl+Alt+F1 (or Ctrl+Alt+F2 or ... or Ctrl+Alt+F6).

Today I started the OS and the files increased a lot, in fact now they are about 6.5GB each.

one part of the output of "tail -f /var/log/syslog" is:

See if some messages are repeated many times (and show them to us):
$ less /var/log/kern.log

It apparently is a problem with the Wifi. You use the firmware that the package "open-ath9k-htc-firmware" provides, right? I use it too but I have no problem. Maybe the hardware is defective...

How much space do you have for / and how much for /home

Is your disk encrypted?

What's the total space of your disk?

Davide, I am just going to state that I respectfully agree to disagree with Mr. Banana, with the caveat that since you do not know the culture of the board you have no way of knowing that I can't believe I'm actually saying this....

It is very probable that my hypothesis ("*maybe* the hardware is defective") is wrong. Do you have another hypothesis? Or do you disagree that the problem "*apparently* is with the Wifi"? That is easy to test:

  1. Disconnect the Wifi (with the related Fn key on the keyboard or physically, e.g., if it is a USB adapter, maybe deactivating Wifi from NetworkManager is enough);
  2. Save some space on the root partition (see https://trisquel.info/forum/trisquel-not-detecting-thinkpenguin-wifi-adapter-after-install#comment-118193 that I have just written);
  3. See if the message keeps on being logged in kern.log, looking at the live output of 'tail -F /var/log/kern.log' or with 'less /var/log/kern.log' after working a little (using Ethernet if the network is needed) or searching for pieces of it with 'grep'.

Pardon me, but so many of my heroes are toppling from their pedestals and you appear to be one of them, Mr. Banana.

It looks a different card than my older model thinkpads, but in the back of my mind I keep having this niggling suspicion that I might not have been completely off base upthread.

If it were my computer or I were setting it up for a friend, I would try editing network interfaces and rc.local (while saving the originals) before giving up on the hardware.

The kernel messages look more "low-level" to me. But, again, it is very probable that I am wrong! Over the years, I have been wrong multiple times in this forum. I would first try deactivating the Wifi, as I wrote in the message above.

I figured it out, Davide!

Mr. Banana and I are in complete agreement that the next thing you need to do is see what happens when you disable your wifi.

I was just too tired and stressed out to understand what he was saying. Editing the configuration files which I posted upthread is how I personally disable proprietary wifi cards but it isn't the only possible option for disabling wifi cards in Trisquel.

I need to get some sleep before I log into my account again. My bad, just me being me again, carry on.
