I too am experiencing buddy errors with EXT4. using 3.2.0-39-generic-pae The volume giving the errors is a RAID 1 setup using dmraid. So I wonder if in this situation there is an issue there. This volume was upgraded from ext3 as well.
I don't see errors in the other ext4 volumes. The errors I am seeing are Apr 2 19:00:14 chamraid01 kernel: [883688.713934] EXT4-fs error (device md3): ext4_mb_generate_buddy:739: group 1627, 29388 clusters in bitmap, 29387 in gd Apr 2 22:10:15 chamraid01 kernel: [895089.919766] EXT4-fs error (device md3): ext4_mb_generate_buddy:739: group 1639, 20958 clusters in bitmap, 20957 in gd Apr 2 22:11:24 chamraid01 kernel: [895158.699530] EXT4-fs error (device md3): ext4_mb_generate_buddy:739: group 1854, 29521 clusters in bitmap, 29520 in gd Apr 2 23:37:59 chamraid01 kernel: [900353.845445] EXT4-fs error (device md3): ext4_mb_generate_buddy:739: group 1592, 22283 clusters in bitmap, 22282 in gd Apr 2 23:38:53 chamraid01 kernel: [900408.376493] EXT4-fs warning (device md3): empty_dir:1929: bad directory (dir #17039929) - no `.' or `..'
