Yes, that is definitely a symptom of the problem I saw. When the
bug strikes, the mod time in the inode is updated, but the page cache
is not invalidated. So an "ls -l" shows the correct mod time, but the
data remains old.

I'm trying to fit in time to install FC3 with a very recent (2.6.10.x)
kernel
to (a) verify the problem is still there and (b) verify my patch still fixes
it.

In the meantime, Sven, are you comfortable with rebuilding your cifs.ko
module? I could send you a version of my patch that should apply cleanly
to 2.6.5-7.145-default.
