I've build xfs_repair from git on lenny and got segfault before my first
email to this list (please refer to first email in this thread) :)

What else I can do to find what differ our two cases?

hd-slave5 ~/devel/xfsprogs/repair # LC_ALL=en_EN ./xfs_repair -v
/dev/cciss/c0d5p1
Phase 1 - find and verify superblock...
- block cache size set to 3446312 entries
Phase 2 - using internal log
- zero log...
zero_log: head block 2 tail block 2
- scan filesystem freespace and inode maps...
- found root inode chunk
Phase 3 - for each AG...
- scan and clear agi unlinked lists...
- process known inodes and perform inode discovery...
- agno = 0
xfs_repair: read failed: Input/output error
can't read block 0 for directory inode 146453
no . entry for directory 146453
no .. entry for directory 146453
- agno = 1
- agno = 2
- agno = 3
- process newly discovered inodes...
Phase 4 - check for duplicate blocks...
- setting up duplicate extent list...
- check for inodes claiming duplicate blocks...
- agno = 0
- agno = 2
- agno = 3
- agno = 1
xfs_repair: read failed: Input/output error
can't read block 0 for directory inode 146453
no . entry for directory 146453
no .. entry for directory 146453
Phase 5 - rebuild AG headers and trees...
- agno = 0
- agno = 1
- agno = 2
- agno = 3
- reset superblock...
Phase 6 - check inode connectivity...
- resetting contents of realtime bitmap and summary inodes
- traversing filesystem ...
- agno = 0
entry "subdir49" in dir ino 437 doesn't have a .. entry, will set it in
ino 146453.
xfs_repair: read failed: Input/output error
