First of all, I would encourage both of you to update to a more recent
kernel. There are some new rpms on the ftp site, I would recommend these:
ftp://oss.sgi.com/projects/xfs/download/testing/Release-1.0.1-PR3/RPMS/RHlinux-2.4.3/
They are based on the updated kernel rpm from redhat 7.1, and contain a lot
of xfs fixes. Secondly the cvs tree development tree is always a good thing
to try when you have problems.
As for what is happening to your file. This is not corruption per se, the
updated inode size made it out to disk, but the data did not. If you do
an xfs_bmap you will probably find there are are no extents in the file.
(xfs_bmap .emacs). It is also not in in kernel buffer corruption problem,
it is because the buffers were not written to disk before the crash, but
the inode size was written in a transaction.
Please try a later kernel as I have not seen reports like this in a
while.
