Hi Carl,
           The best way to see what is going on is to see what log thinks it 
has. You must have got a message indicating the inode number and other details 
of the extent as indicated by the source.
 
         if(!rt && !gotp->br_startblock && (*lastxp != NULLEXTNUM 
<http://fxr.watson.org/fxr/ident?v=linux-2.6.11.8;i=NULLEXTNUM> )) {
               cmn_err 
<http://fxr.watson.org/fxr/ident?v=linux-2.6.11.8;i=cmn_err> (CE_PANIC 
<http://fxr.watson.org/fxr/ident?v=linux-2.6.11.8;i=CE_PANIC> ,"Access to block 
zero: fs: <%s> inode: %lld "
                        "start_block : %llx start_off : %llx blkcnt : %llx "
                       "extent-state : %x \n",
                        (ip 
<http://fxr.watson.org/fxr/ident?v=linux-2.6.11.8;i=ip> 
->i_mount)->m_fsname,(long long)ip 
<http://fxr.watson.org/fxr/ident?v=linux-2.6.11.8;i=ip> ->i_ino,
                         gotp->br_startblock, gotp->br_startoff,
                         gotp->br_blockcount,gotp->br_state);
        }

 
 
Can you attach the hex dump of complete log with inode and extent information ? 
I want to see what has gone into the log for the operations on this inode. It 
could be that the extent map was corrupted just before shutdown or something in 
recovery screwed up.

I've been hit by a bug installing FC6test4. It will hold us back upgrading
since we use XFS for our home-dirs at work.

Here is the link to the bug report at redhat's bugzilla:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=211086

Here is dmesg when I try to read the file /var/lib/rpm/Packages:

I have the actual partition bzip:ed.

Unpack it and dd to a 4GB logical volume and try to read from
/var/lib/rpm/Packages
