There seems to be an issue with the rt2x00 driver or something related.
From OpenWRT 23.05.4 and 23.05.5 the speed increased from 1 Mbps to 5 Mbps, but during a speed test, the router reboots even 60 seconds after booting.
MT7620 router.

Openwrt supports only one device using this, or should we dig up the crystal ball?
You mean which router?
Always mine. https://shop.gevaelettronica.it/en/4-battery-poe
When I find the time to figure out how to commit I will put it in the managed routers.
The defect also does this in version 23.05.4
It does it much less perhaps because it runs much slower (the speed test)
I was able to log the moment of the reboot.

mybe cause is my geva_sleep
I lost the source of that file,
I use it for flashing leds via sh.
What is the syntax for writing this in the mt7620.mk file?
CONFIG_BUSYBOX_CUSTOM=y
CONFIG_BUSYBOX_CONFIG_USLEEP=y
The problem is the same even if I replace geva_sleep with usleep.
The cause seems to be the sh script I use to control the LEDs.
Could it be that the command called cyclically during the speed test is the cause?
swconfig dev switch0 port 0 show
#!/bin/sh

# echo "led"

I abandoned 23.05.5,
I could not get it to work.
I always have kernel panic
The driver definitely has problems.
The driver does not support wpa3 (more accurately pmf/11w}
Probably cpu heats in 10yo dustball too much.
Rt2800soc ( not rt2xyz ) only, you can add documentation request to add caveat to wiki pages.
I did not understand a single word.
Up to version 23.05.4 it worked correctly.
Since version 23.05.5 the command
iw phy0-ap0 station
Repeated in 1-second cycles, creates kernel panic
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
on 23.05.4 or 23.05.5 ?
Now i have only device with 23.05.4
More about configs, .4 and .5 are interchangeable and should not impose new memory leaks etc.
EDIT: adjusted title
Something has changed because it no longer works.
There is a new bug

Dmesg output looks like a memory leak. Nothing in your config says like "dynamic huge memory".
check changelog (superfluously nothing towards encountered damage)
maybe it is in mainline kernel then?
Do you want an hardware to test ?
Please take a look:
Your kernel oops log shows you are using the master branch, not v23. If possible, please attach the oops log from OpenWrt v23.

You mean I have forgotten this command?
# Select a specific code revision
git branch -a
git tag
git checkout v23.05.5
The newly introduced init script will prevent calling get_random_u32_below() in arch_align_stack().
Will I find it in future versions ?
Will I be able to try again from v23.05.6 ?
