Attached is the output of

from a Gentoo hardened Linux server running at a bare metal server since
3 yrs. The system contained 2x 3.84 TiB NVMe drives, / was a raid1,
/data was configured as raid0.
I upgraded yesterday from kernel 6.8.10 to 6.8.11.
The system does not recover from reboot in moment.

It recovered eventually, I switched to 6.9.2, which runs fine so far.
But these are new log messages:

That looks exactly the one Linus recently reported
(https://lore.kernel.org/linux-btrfs/CAHk-=wgt362nGfScVOOii8cgKn2LVVHeOvOA7OBwg1OwbuJQcw@mail.gmail.com/)
Unfortunately he is reproducing it with latest master, so I'm not sure
if v6.9 is any better.
Meanwhile if you can reproduce the problem reliably, I can craft several
debug patches for you to test, but I'm afraid it's not that reproducible...
Thanks,

It could be similar to what was fixed in ef1e68236b91 ("btrfs: fix race
in read_extent_buffer_pages()"), also hard to reproduce. The stack
traces are the only clues we have now.
