3.3-rc4+: Reported regressions from 3.2

Hi all,

We definitely aren't 100% in business yet with the tracking of regressions,
but since the Bugzilla is operational again, we can collect reports at least.

I'd like to use this opportunity to thank Maciej Rutecki and Florian Mickler
for their hard work on the regression tracking and to clarify some things that
seem to have caused some confusion to happen recently.  Namely, we use the
kernel Bugzilla (https://bugzilla.kernel.org) for the tracking of regressions
for the simple reason that our scripts generate the lists that are posted
(like the one below) out of Bugzilla entries created by us (and sometimes
by other people).  Those entries are used by us as a storage of information,
so we're going to add them even though some kernel developers don't seem to
like that.  We don't require developers to actually use those entries for
handling bug reports, we only need people to let us know when they should be
closed, because the bug has been fixed in the Linus' tree, or when there's
a patch available for the bug (in which case we mark it as "resolved", but
we don't close it just yet).  There is no reason for you to be openly hostile
to Maciej, who's been creating those entries recently, because he's just been
doing his job.  However, you may not want us to track kernel regressions at
all, in which case please let us know about that and we will find some other,
presumably equally interesting things to do. :-)

Yes, we might have been more verbose about what _exactly_ we've been using the
Bugzilla for and what our workflow is, but at the same time people might have
been a bit less harsh to someone who's been doing a service to the community,
completely voluntarily.



This message contains a list of some regressions from 3.2,
for which there are no fixes in the mainline known to the tracking team.
If any of them have been fixed already, please let us know.

If you know of any other unresolved regressions from 3.2, please let us
know either and we'll add them to the list.  Also, please let us 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.

As you can see, there is a Bugzilla entry for each of the listed regressions.
There also is a Bugzilla entry used for tracking the regressions from 3.2,
unresolved as well as resolved, at:


Please let the tracking team know if there are any Bugzilla entries that
should be added to the list in there.
