Yeap, no problem. It worked. I mean, recorded on external usb stick... But...
On my laptop I have kernel 6.6.36 and rc6+branch...
Uhm... Yesterday I switched back to 6.6.36 after wrote the email,
well, not exactly, I usually work with 6.6.36 and yesterday rebooted
with rc6 to test the branch patches (so the sluggish issue weeks ago,
so I didn't move from 6.6.36).
Anyway, after wrote you the report while watching the "live action", I
rebooted 6.6.36.

Anyway, tried right now with bpftrace and I can't replicate it. Kernel
exactly the same. No recompilo or so on...

I just can think about a few LibreOffice git subvolume deleted
(~215000 files), and a few created.
A few tens of giga deleted of files (mp4 and mkv). Uhm... dunno if it
could be related or something changed on BTRFS layout.

Well, I have the nighlty snapshot (well, it's not on every subvolume
of the fs). I ran tar on that, and we see.

I tell you in a few hours. In the meanwhile I keep running rc6+ and
see if something happens.
