No internet/trackpad use after kernel upgrade

miomeows · 2025-06-13 18:03:18

Hello there--I have a Dell Inspiron 15 3520 I am test driving Arch Linux on before possibly making the attempt to replace Windows as my daily driver on my desktop computer. (I used Mint for years on an old Macbook, so I'm not completely inexperienced with Linux, but I might as well be for how much Mint held my hand.)

For my first Arch install, I used the archinstall script, and it worked great for a couple of months, but a couple weeks ago I decided to reinstall Arch the actual way as a test to see how much I'd learned. That worked great too until my first kernel upgrade from 6.14.7 to 6.14.9, after which I rebooted my machine only to find I could only connect to the loopback network interface; both wifi and ethernet (via a USB adapter) and the trackpad did not work. A downgrade back to 6.14.7 fixed the issue, and then I installed the LTS kernel and that also worked, which I've been using ever since. That feels more like a bandaid fix, however, and I'd like to learn how to fix it properly.

I would wager a guess that I'm missing some package that is causing the internet and trackpad to not work, but all my googling has turned up a bunch of different responses and I'm a little overwhelmed. Any help is much appreciated; I am extremely willing to learn what I'm doing wrong!

Hi, welcome!

There is a possible ACPI bug in the kernel. Let's take a look on kernel error by going to v6.14.9 then type this in terminal

sudo dmesg

Find for any red text, then send it here

I'm not entirely sure what I did, but it does seem to have fixed itself somehow. It was broken on 6.14.9, I updated to 6.15.2, it still didn't work after a reboot, but after a second reboot it started working again. I'm so sorry to have wasted your time (and led any future googlers who find themselves here answerless), but I guess I'm good for now.

There is still a line of red text in that command, which I will post here for you if it would help in any way in fixing bugs.

[    1.767891] ahci 0000:00:0e.0: probe with driver ahci failed with error -12

(Edit: should I still mark this thread as "solved" in the title even if, uh, there's no solution in the thread to be found?)

No worries! Glad to know the bug already solved. If you still face the issue, you can always provide the error logs from dmesg (as I mentioned earlier).

Yes. If you still have the error, you can create another thread and provide the logs.
