^^^^^^^^^^^^^^^^^^^^^^^^^^
This should be PR_1_EA_BLOCK_ONLY_CSUM_INVALID. This was discovered
again via the tst_problem unit test in the e2fsprogs regression test
suite:
LD_LIBRARY_PATH=../lib DYLD_LIBRARY_PATH=../lib ./tst_problem
*** Duplicate in problem table:
curr code = 0x0001006a: Extended attribute @a @b %b passes checks, but checksum for @i %i does not match.
*** prev code = 0x0001006a: Extended attribute @a @b %b checksum for @i %i does not match.
*** This is a fatal programming error in e2fsck
