I have successfully reproduced the issue and Eric Sandeen has taken a look at
the output of xfs_db below:

xfs_db> inode 136
xfs_db> p
core.magic = 0x5858
core.mode = 0100644
core.version = 2
core.format = 2 (extents)
core.nlinkv2 = 1
core.onlink = 0
core.projid = 0
core.uid = 0
core.gid = 0
core.flushiter = 2
core.atime.sec = Thu Nov 12 19:23:33 2009
core.atime.nsec = 108456210
core.mtime.sec = Thu Nov 12 19:23:33 2009
core.mtime.nsec = 108456210
core.ctime.sec = Thu Nov 12 19:23:33 2009
core.ctime.nsec = 108456210
core.size = 827
core.nblocks = 1
core.extsize = 0
core.nextents = 1
core.naextents = 0
core.forkoff = 0
core.aformat = 2 (extents)
core.dmevmask = 0

core.noatime = 0
core.nodump = 0
core.rtinherit = 0
core.projinherit = 0
core.nosymlinks = 0
core.extsz = 0
core.extszinherit = 0
core.nodefrag = 0
core.filestream = 0
core.gen = 0
next_unlinked = null
u.bmx[0] = [startoff,startblock,blockcount,extentflag] 0:[0,86,1,0]

I am now trying a patch provided by Eric and Christoph Hellwig to flush the
dcache. I will add more information as the problem keeps occurring.
