[SOLVED] kernel & hostapd: kernel Oops MT792x

My 6GHz AP on hostapd with Mediatek stopped working after an update, hostapd survives SIGKILL and my device can't shut down. Tried 2 times and it's the same. The 2nd time I stopped the service first (& waited for it to timeout), still took some time but at least it shut down.

Re: [SOLVED] kernel & hostapd: kernel Oops MT792x

There's also a 2.4GHz AP with Intel, has kernel warnings and "failed to remove key (2, ff:ff:ff:ff:ff:ff) from hardware (-22)" but it happens all the time and had no effect.

Re: [SOLVED] kernel & hostapd: kernel Oops MT792x

Is this a new issue? Do you also observe this issue when running the 'linux-lts' kernel?

Is the issue also present in the latest kernel release candidate?

sudo pacman -U https://pkgbuild.com//\~gromit/linux-bisection-kernels/linux-mainline-6.14rc3-1-x86_64.pkg.tar.zst

This way we don't start investigating a bug in detail which may already be fixed in a newer version ..

(note that this installs the kernel as linux-mainline, so you need to configure your bootloader to boot it (for example via grub-mkconfig -o ... or by writing the systemd-boot loader entry))

Re: [SOLVED] kernel & hostapd: kernel Oops MT792x

I just came back to this and upgraded kernel to 6.13.3.arch1-1, the terminal is now kinda broken (e.g. can't scroll)

$ networkctl
WARNING: terminal is not fully functional
Press RETURN to continue

EDIT: This was because I'm using ghostty, the terminfo was not available on the server. https://ghostty.org/docs/help/terminfo#ssh

I installed the mainline but the device won't boot. I'll need to take it out and plug it into a monitor to see what's happening...

Re: [SOLVED] kernel & hostapd: kernel Oops MT792x

If you want some help diagnosing these issues (there seem to be multiple) you'll need to post some more information... Could you for example post the 'dmesg' output of one of the problems?

Re: [SOLVED] kernel & hostapd: kernel Oops MT792x

The mainline kernel won't boot because it can't open my BTRFS partition. The UEFI boot args were read from /etc/kernel/cmdline by bash so I'm pretty sure there is not a typo. (Also tried typing them in manually.)
The mkinitcpio config has the filesystems hook and stable release works, do I need to change something?

p.s. The warning about the broken terminal was gone when I was on the device directly, now it doesn't happen over SSH either. (I upgraded some packages and the UEFI firmware while I was on the machine.)

Here's the photo of the mainline kernel boot error:

Re: [SOLVED] kernel & hostapd: kernel Oops MT792x

The issue in the OP seems to have been fixed by kernel 6.13.4.
EDIT: Spoke too soon, blew up after a few minutes of use.

Re: [SOLVED] kernel & hostapd: kernel Oops MT792x

The issue in the OP has already been found by others, a patch will likely be in wireless-next (6.15? oof).

Re: [SOLVED] kernel & hostapd: kernel Oops MT792x

Are you confident to do the bisection on your own or do you need some help?
If you want we could also provide you with pre-built kernel images for you to test (which greatly speeds up the test time)  

Good info to get you started is:
- https://docs.kernel.org/admin-guide/rep … sions.html
- https://wiki.archlinux.org/title/Kernel … egressions

Since we already determined that there are multiple issues at hand here (sleep + brightness) I would like to have a look at the sleep issue.

Additionally it would be good to see if the latest mainline kernel is affected:

sudo pacman -U https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-mainline-6.14rc1-1-x86_64.pkg.tar.zst

(note that this installs the kernel as linux-mainline, so you need to configure your bootloader to boot it (for example via grub-mkconfig -o ... or by writing the systemd-boot loader entry))

Edit: Nevermind, I somehow missed the previous post ...
