[NOTE:
 We already have a bug entry for tracking regressions from 3.0:

 http://bugzilla.kernel.org/show_bug.cgi?id=40982

 but there are no reports linked to it, mostly because Maciej is on vacation,
 but also because the frequency of reporting regressions has been low
 recently.  So, if you're seeing a regression from 3.0, please let us know.]

This message contains a list of some post-2.6.39 regressions introduced before
3.0, 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 post-2.6.39 regressions, 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.
