2.6.28-rc1-git1: Reported regressions 2.6.26 -> 2.6.27

[Rafael J. Wysocki]

[Here's something new, a list of regressions introduced between 2.6.26 and
2.6.27.  We haven't fixed all of them yet and they're still being reported.
Also, they need to be fixed as well as those introduced later (although they
may be considered as "less important").

Quite frankly, I don't know how this is going to work out, but I thought
it's worth trying.  Enjoy! ;-)]

This message contains a list of some regressions introduced between 2.6.26 and
2.6.27, for which there are no fixes in the mainline I know of.  If any of them
have been fixed already, please let me know.

If you know of any other unresolved regressions introduced between 2.6.26
and 2.6.27, please let me know either and I'll add them to the list.
Also, please let me know if any of the entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

commit fd6149d332973bafa50f03ddb0ea9513e67f4517
Author: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi>
Date:   Thu Oct 23 14:06:35 2008 -0700

    tcp: Restore ordering of TCP options for the sake of inter-operability
    
    This is not our bug! Sadly some devices cannot cope with the change
    of TCP option ordering which was a result of the recent rewrite of
    the option code (not that there was some particular reason steming
    from the rewrite for the reordering) though any ordering of TCP
    options is perfectly legal. Thus we restore the original ordering
    to allow interoperability with/through such broken devices and add
    some warning about this trap. Since the reordering just happened
    without any particular reason, this change shouldn't cost us
    anything.
    
    There are already couple of known failure reports (within close
    proximity of the last release), so the problem might be more
    wide-spread than a single device. And other reports which may
    be due to the same problem though the symptoms were less obvious.
    Analysis of one of the case revealed (with very high probability)
    that sack capability cannot be negotiated as the first option
    (SYN never got a response).

I believe this to be a valid bug report, but there doesn't appear to be
anyone to be interested in working on it.  It can be killed off.
I no longer care about it.
