Did you have the XFS_DEBUG option on? Without it, the filesystem with 
realtime does not die right away, but hangs or crashes later.

Vanilla 2.6.16.19 without the lazy-counters option:

Assertion failed: ((tp)->t_blk_res) > 0, file: 
/home/rk/linux-2.6.16.19/fs/xfs/xfs_bmap.c, line: 5452

It looks like it never worked.
