Random reboot after 15 days up and running

Verylongusername · November 10, 2025, 10:20pm

Hi All,
Since 24.10 I have had a few ramdom reboots (after several weeks up), the last one was after two weeks up with no issues. I dont know if the logs (gathered from an external syslog server) say someting about the cause. I am just curious as it usually runs for months with no issues.
The hardware is Zbtlink ZBT-WE1326 (mt7621) running OpenWrt 24.10-SNAPSHOT r28628-cc1b909a6b (custom build on may 1st, right after 24.10 service release 02 I believe)
These are the logs I got:

There should be something before. Backtraces point to the backtracer itself only.

lib/list_debug.c:29 __list_add_valid_or_report+0xa4/0x128
Nov  9 21:03:18 WIFIH kernel: [1770358.034780] list_add corruption. next->prev should be prev (8101f0bc), but was 00000122. (next=80c9fb74).

Looks like a memory pointer reference error in a list iterator. Instead of pointing to the address of the item 122 in the list, it points to the item index (122).
But not much clues from which module it comes.

As you are using an old build, the first thing would be to upgrade to a current version, as the bug may be already fixed.

Hi , surprisingly it just happened again a few minutes ago. This time logs also show an error that says something about a bug.... I dont know if if has something to do:
I will update to lastest service release as soon as possible as suggested.
Thank you!

Can you get 24.10.4 24.10-SNAPSHOT after it or SNAPSHOT to crash.
What is in diffconfig script output?

I dont know where the diffconfig script is, I tried to run it but it is not in the path.
Today I have had another reboot/crash, it is like a snowball falling the mountain that it is getting bigger and bigger... from just one random reboot in months to almost one everyday....
I have just downloaded and compilled current 24.10 branch from git and will flash it tonight when the router is not being used.
I hope with today's build I dont have reboots everyday, I will be ok with the previous state of the things of one reboot in months.
Thank you all for your help!

That crash seems to be coming from the kernel code, so quite possibly it is already fixed upstream.

brada4 · November 12, 2025, 6:15pm

In scripts/ directory as most utility scripts.

antonk · November 13, 2025, 1:04am

There have been some patches for list corruption on mt76, e.g.:

Might be related and if so then i believe this is fixed in current stable release.

Verylongusername · November 13, 2025, 9:38am

Well i have compiled and sysupgraded keeping current settings. Everything went ok, now I only have to wait and see

Verylongusername · November 20, 2025, 12:52pm

After the upgrade I have had no crash for 7 days. I think this is solved. Thank you
