With which kernel version did you run the test?

I went back to 2.6.23 and the same assfail happened with somewhat different 
call trace:

Assertion failed: xfs_trans_get_block_res(tp) > 0, file: 
/home/rk/linux-2.6.23/fs/xfs/xfs_bmap.c, line: 5523

I tried to go back to 2.6.22.19 and older, and the test did not run at all 
failing to mount:

XFS: bad version
XFS: SB validate failed

Any suggestions?
