Any news here?

I see that there's a debug patch attached, but for testing a kernel package would be needed.

I thought this may had been fixed by other changes that landed in the meanwhile. It seems not, since the kernel is 5.9 in that trace. Ok, I'm not very familiar with building a kernel package, but I think I managed to do it correctly: https://build.opensuse.org/package/show/home:fdmanana:btrfs-debug/kernel-def... Is someone able to grab the kernel package from there and test it? When the problem reproduces, I will need the full dmesg (not just the stack trace with the crash or warnings).
