Could you try to use one of the last vanilla kernel (for example, 3.7.1)? To be honestly, I tried to reproduce the issue on 3.6.0 version but without any success. And I know that such issue was reported on 3.6.8 kernel version also. But this issue has not stable reproducing in the case of 3.6.8 kernel version. > 2. nilfs-utils version: nilfs-utils-2.1.4 > 3.
