Comment # 101 on bug 1063638 from Ronan Chagas

Guys, let���s calm down.

First, I am facing this problem since 2016 and I completely support the idea
that BTRFS as used by openSUSE is not ready for production. I saw this bug in
every setup with both Leap and Tumbleweed.

However, the workaround cannot be simpler. Just disable quotas. This fixed the
problem in 100% of my cases. You will have a stable system while the devs fix
the problems. The only downside is that you will loose the snapshot auto
cleanup feature, which I, personally, do not care.
