It does. Will need to take a look - if I'm lucky, maybe some
firmware is now needed. If not, the joys of finding an easily
reproduceable test case: perhaps the time to untar firefox from nfs,
followed by finding a "good" kernel (and I suspect this goes back
some time).
At the moment I don't think I've seen the problem on other machines,
but I suppose I ought to check in case it is something on the server
that is the problem.
Objectively, less important for the general user than the
libssh2/vlc problem - so I'll concentrate on that.
