--- Comment #6 from Theodore Tso (tytso@....edu) ---
This message generally means the file system has been corrupted.

[ 1510.269945] EXT4-fs error (device sda1): ext4_validate_block_bitmap:395:
comm main: bg 17: block 557056: invalid block bitmap

And that would explain why all of the kernel versions are complaining.   It
would be useful to see the output of dumpe2fs or running e2fsck -fy on the file
system.

Don't be too quick to assume it's a kernel bug before checking to see if the
file system is just corrupted, and the kernel really is correct in complaining!
