Theodore Ts'o : I noticed that this bug is more likely to happen on partitions that does not have many space left, in case that this give you some hint. I have a 30 Gb partition which has only 3 Gb left. The bug can be reproduced immediately each time on that partition. I have a 700 Gb partition with 500 Gb left, it's pretty hard to reproduce the issue on it.
