Quite strange. I didn't see that problem here. ---- btrfs/006 12s ... 13s Ran: btrfs/006 Passed all 1 tests --- Can you retain the scratch mounted and check what is the output of 'btrfs fi show -m' (when the SCRATCH is mounted). OR /proc/fs/btrfs/devlist (in case if you have that) would help to debug this. OR could you restart test with a wipe all disk ?
