This is this chunk of code:
for (bsy = mp->m_perag[agno].pagb_list, n = 0;
c01970e2: 31 db xor %ebx,%ebx
c01970e4: 8b b5 e4 01 00 00 mov 0x1e4(%ebp),%esi
c01970ea: 8b 54 06 20 mov 0x20(%esi,%eax,1),%edx
n < XFS_PAGB_NUM_SLOTS;
bsy++, n++) {
if (bsy->busy_tp == NULL) {
c01970ee: 8b 4a 08 mov 0x8(%edx),%ecx
It looks like bsy is NULL, which means either a corruption problem
(agno too large),
or a memory allocation problem during mount - did you get any error
messages when
you mounted the filesystem? Had you performed much I/O before this
happened, or
was the cpio the first thing you did. If this structure is missing
then chances are you
would not get far before dying. We have already referenced other
fields in the m_perag[agno]
structure, so I lean towards pagb_list itself being NULL.
Can you send me the output of mkfs if you still have it, or failing
that, the output
of xfs_growfs -n /xxx where /xxx is the mounted filesystem.
This chunk of code is new, you may have found a hole in it - although
I have been running
it for a couple of months here without problem. It could also be
something specific to
the aa kernel, I have not looked at this merge of XFS.

i just created LV, formated it with xfs , extended it , mounted it,
extended the fs , and started to transfer my old /opt to the LV with cpio
there were no complains from mount or xfs_growfs
and i have no the output from mkfs.xfs
[root@svetljo log]# xfs_growfs -n /opt
