Driver mt7921e frequently crashes

Frisk17 · 2024-06-30 09:05:48

Device: ASUS TUF Gaming A15 FA506IHRB_FA506IHRZ
Kernel Version: 6.9.7-arch1-1

MT7921 802.11ax PCI Express Wireless Network Adapter wifi abruptly stops working with the kernel log

mt7921e 0000:03:00.0: Timeout for driver own
mt7921e 0000:03:00.0: driver own failed

After rebooting the wifi device disappears for 1-5 boots (sometimes more) from lshw. There are no clear steps to reproduce this and it randomly happens.

Both fast startup and hibernation are off.

Esp. since the behavior is "random" the context will matter if you want an informed comment - "-p err" will only say "yeah, happened"

None of that is inherently relevant to your wifi issues.

I'm sorry, I'm not sure what you meant by this but if it's about posting logs with warning priority here are the logs at a higher priority level: https://0x0.st/Xa2p.txt

Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Frisk17 · 2024-07-02 13:00:00

Yes, I've uploaded the full log for that boot at: https://0x0.st/Xa2p.txt

The NIC shows up, scans and connects effortlessly and pretty much exactly 7 minutes later stops responding - smell like powersaving.
Try to add "mt7921e.disable_aspm=1 pcie_aspm=off" to the https://wiki.archlinux.org/title/Kernel_parameters

Frisk17 · 2024-07-02 15:57:17

The issue still persists although it did work for longer. Here are the logs from that boot: https://0x0.st/XaLC.txt

seth · 2024-07-02 20:14:26

To test whether this is power-saving related at all, try to throw the NIC a life-line and keep "ping google.com" running in the background.
Also, in case some tool sets that

iw dev wlp3s0 get power_save
iw dev wlp3s0 set power_save off

Frisk17 · 2024-07-03 10:50:46

iw dev wlp3s0 get power_save

This outputs "on" on boot, is this expected even with the mt7921e.disable_aspm=1 pcie_aspm=off kernel parameters?
The output was still off after the driver failing and being set manually with that command.

To test whether this is power-saving related at all, try to throw the NIC a life-line and keep "ping google.com" running in the background.

The driver still failed even with the ping command running in the background.
Also, if I don't shutdown soon after the driver failing the kernel seems to also crash (the caps lock light starts blinking and everything freezes and I'm not able to switch into any other tty either). I tried testing if the LTS kernel fixed anything but it doesn't seem like it. The journal log (by using -b -1) doesn't contain any information regarding the crash, the last message is the driver own failed.

Did you get anywhere with this? My system has been very stable since I built it 6 months ago, up until this morning when I woke up to this error and the wifi wouldn't connect.

Then today it happened mid-session and completely locked the whole PC up.

This is my log:

https://0x0.st/XBX-.txt

My mobo is an Asus ROG Strix B650E-I

I don't think I'm doing any sleep stuff, it's a desktop and I didn't set it up as such

I do have this in sway that turns the output off:

exec swayidle -w \
        timeout 300 'swaylock -f -c 000000' \
        timeout 600 'swaymsg "output * power off"' resume 'swaymsg "output * power on"'

If it's a regression, but not the kernel, the cause might be https://archlinux.org/packages/core/any/linux-firmware/ which was updated ~3 weeks ago.
I didn't check whether the relevant file changed but you could compare the FW version against the one loaded in an older journal and/or simply try to downgrade linux-firmware

Frisk17 · 2024-07-08 07:21:53

I found this message on one of the boots where the wifi device is not detected, although I didn't find messages like this on other boots where the device is not detected

No mt7921e message should show up if the device doesn't even show up because the module alias won't get triggered.
Did you try to downgrade linux-firmware?

Frisk17 · 2024-07-09 09:31:14

Did you try to downgrade linux-firmware?

Yes, I did downgrade linux firmware to linux-firmware 20240510.b9d2bf23-1 but the issue still persisted.
