There's one for each core. It freezes everything on the desktop including the
mouse and keyboard.



I observed the same problem, and asked on the spanish support group of
Telegram, and someone recommend to execute:
sudo btrfs quota disable /

Yesterday a guy that has disabled the btrfs quota must to reinstall,
because the root partition goes corrupted.

In Opensuse are other guys with the same problem:
