Description JoeS 2025-02-21 16:28:31 UTC

I am running Tumbleweed 20250216 with kernel 6.13.2 and while accessing a USB device I received the following kernel BUG messages in the journal:

AFTER that the kernel is tainted with a value of 128, but the system is still up and running but since the kernel is tainted I rebooted.


Before updating tumbleweed to 20250216 with kernel 20250106 I was using tumbleweed 20250106 with kernel 6.12.8 and I saw MANY USB issues which resulting in USB drives getting corrupted.    Switch tumbleweed 20250106 back to kernel 6.11.8 resulted in all the USB issues going away.

I don't know if those issues are related or not but it seems that 6.12.8 had LOTS of USB type issues which I had hoped were addressed with 6.13.2.

Please let me know if you need any further information.

Thanks!

Correction - should have said

One common factor is a python program was running which reads a bunch of files from a USB drive.

Comment 3 JoeS 2025-02-28 21:32:56 UTC

Had this happen a 3rd time now with kernel 13.2.

The common factor is always a python program running which reads a bunch of files from a USB drive.

When I boot back to kernel 6.11.8 I do not encounter the issue.

Comment 4 JoeS 2025-03-06 00:19:26 UTC

Do you need any more info for this ?

Comment 5 Narendran Gopalakrishnan 2025-03-14 04:46:08 UTC

I had a similar issues with Fedora41 kernel 6.13.4 as well as 6.13.5, when using rclone to sync from USB drives. It was consistently reproducible. Reverting back to kernel 6.12.9 solved the issue.

Good to know that kernel 6.12.9 is resolved your issues.

I have not tried that kernel and have just stayed on 6.11.8 which I've been using for months now without the issues.

I wonder if I have this in the wrong category as there has been no activity or update on the bug report ?

This is hard for me to say - the issue could even be in a module, as page allocator is likely well tested by now. I believe it is probably better to report the bug under some category (as you have done), rather than not at all. The lack of activity might also mean they have fixed this bug in a latter version, or they give priority to bug reports in the mainline kernel, or if the number of users reporting the bug is not critical - again just shooting in the dark.
