It's been failing on mainline kernels for a long time. In fact, i think it's been failing since it was created. But it's not failing due to btree corruption - it's failing because mkfs is not leaving enough space in the AG that contains the log for sanity checks to pass. i.e. that there are always a minimum of 4 blocks of freespace in an AG. This is not actually a problem - the log takes the entire AG, so allocation will never occur in it, so having less than 4 blocks of free space in the AG is just noise in this case. It's never bubbled to the top of my list to fix... > I'm going to take a look at it, but let me know if anybody has already > found/fixed it. If it is failing the check_scratch_fs stage, then it is most likely the above issue. The corrupted btree problem that the test was writen for caused the system to ASSERT fail or crash - i.e. it didn't even run to the point of checking the fs....
