Hello, somewhat of a newbie here, but when I do
journalctl -f I keep getting this error every 5 seconds:
Nov 05 22:02:35 TomXPSHost kernel: ERROR @wl_cfg80211_get_tx_power : error (-1)
Nov 05 22:02:35 TomXPSHost kernel: ERROR @wl_dev_intvar_get : error (-1)
Nov 05 22:02:35 TomXPSHost kernel: ERROR @wl_cfg80211_get_tx_power : error (-1)
Nov 05 22:02:40 TomXPSHost kernel: ERROR @wl_dev_intvar_get : error (-1)
Nov 05 22:02:40 TomXPSHost kernel: ERROR @wl_cfg80211_get_tx_power : error (-1)
Nov 05 22:02:40 TomXPSHost kernel: ERROR @wl_dev_intvar_get : error (-1)
Nov 05 22:02:40 TomXPSHost kernel: ERROR @wl_cfg80211_get_tx_power : error (-1)
Its very odd and not being famliiar with the kernel, I don't know what the cause is. My computer (dell xps 13 laptop running Linux 4.2.5-1) has also been getting very overheated quickly, and where it used to be totally silent before, now has a constant loud fan blowing. I'm not sure if these two things are related, but it didn't seem like a coincedence as they both started at the same time.

Is this a new arch linux installation? If not, did this error happen after pacman -Syu?
Try running the lts kernel and see if the problem still happens then.

this is not a new installation. and yes it occured after doing a pacman -Syu. how exactly do I switch to lts? When I tried to do that before, my arch wouldn't boot after saying it couldn't find vmlinuz

Just install target linux kernel using pacman.
pacman -S linux-lts
This will generate kernel and initramfs images in your /boot folder
Then regenerate your bootloader configuration file.
If you installed grub you can do so using :
grub-mkconfig -o /boot/grub/grub.cfg
Check commands output and make sure vmlinuz-linux-lts and initramfs-linux-lts.img are in your /boot folder.

This may sound really dumb, but how do I ind out with laoder I have ? I installed arch a few months ago, and it no longer shows a boot up screen after the problems I said before when trying to isntall LTS
Offline
Check your /boot folder content.
You'll find a folder corresponding to the bootloader you installed. /boot/grub for grub, /boot/syslinux for syslinux, etc.
Or your can query the pacman database
pacman -Qs bootloader
EDIT:
You may also have used the systemd included bootlader: systemd-boot. Which corresponds to a /boot/loader folder if activated.

Concerning the error, it seems to be related to your wifi driver.
Check pacman log (/var/log/pacman.log) to find out which package were updated when the problem started to occur.
It's probably one of the packages described here: https://wiki.archlinux.org/index.php/Broadcom_wireless given that XPS 13 laptops have broadcom wifi chipset built in.
In case you find a corresponding entry in the pacman log, you can downgrade it and see if the problem remains.
Go to pacman cache folder, which contains all packages you installed before
cd /var/cache/pacman/pkg
and install back the previous version
pacman -U packagetoinstall
Offline
I realized it is the broadcom packaes, and seems to happen with both, broadcom-wl, and broadcom-wl-dkms. And I have rebooted my computer a few times, so the older version is no longer in my cache. Am I able to deownlaod older versions from aur?
As for the bootlader, I only see an EFI/ folder as well as a loader/ folder does that mean I don't have grub? because grub2 is definitely isntalled.
Offline
All installed packages are stored in /var/cache/pacman/pkg and remain here unless you explicitly clean it using an appropriate command or script.
See https://wiki.archlinux.org/index.php/Pa … kage_cache.
This allows you to revert to an older package on demand (using pacman -U) in case you experience this kind of problem.
Concerning the bootloader:
Your /boot content shows a /loader folder so you probably configured systemd-boot instead of grub2 even if you download grub2 package.
Both do the job but do not get them mixed up.
I recommend you to read related wiki article https://wiki.archlinux.org/index.php/Boot_loaders to see how to configure your bootloader and how to boot into an alternative kernel if needed.

ok thanks, I figured out the bootloader stuff I think but haven't tested trying to boot into LTS yet. For the cache, my wl packages aren't there , I think I cleared the cache after there was a package corruption error or it may have happened because I was trying to save space in my root partition.
Offline
Well.. be careful with pacman cache. Arch is a rolling release and having downgrading solution is often a good workaround.
Use the command:
paccache -r
when you intend to save space.
This keeps the 3 most recent versions of each package and clean the rest of them.
That said, I seems to be this solution to retreive old package : https://wiki.archlinux.org/index.php/Arch_Linux_Archive
I never used it so I can't help you with that..
Offline
Moving to linux lts seemd to have solved the issue.
EDIT: actually seems that neither of the wl packages were loaded, after loding them the error remains even with LTS kernel.
