(In reply to Goldwyn Rodrigues from comment #9)
I have been trying to recreate this issue (especially the trace in comment
#3) but have not succeeded so far.

Well, I don't expect this to be reproducible within a few minutes.
It happened here in my build server after an uptime of more than two weeks.

Richard: Does btrfs check report your filesystem is healthy?

The check upon boot reports it as healthy.
Since it is my rootfs I cannot run the check directly.

Ronan: Are you getting these backtraces in the kernel log as well?

btrfs balance is a relatively I/O intensive operation because it has to move
around chunks. However, if the tree is balanced frequently, then each
balance should not take as much time.

The reporter here seem to observe the opposite. ;-)
