Ok now with same config kernels 3.16, 3.14 and 3.10 fail in same spot. It failes around rsync --delete or something command, dunno how to find what it is I looked at iotop. So let me reiterate: One automated operation that worked after fsck every day for months with kernel 3.10 started making problems since I started using 3.16 BUT it makes kernel Oops even if I go back to 3.10. The only funky thing I did was having txmod=wa for few days in /etc/fstab but that was before these problems. Could it be that some corrupted file makes this, unseen by fsck? I can reformat this partition but I suspect that problematic file is on my /. And then we wouldn't have a test case to reproduce this oops :) Is there any way to record all IO requests to find what exactly does this? This is Oops from 3.14: Nov 3 18:57:40 krshina3 kernel: [ 179.693947] ------------[ cut here ]------------ Nov 3 18:57:40 krshina3 kernel: [ 179.694212] kernel BUG at fs/reiser4/plugin/item/ctail.c:669!
