2.6.28-rc5: Reported regressions from 2.6.27

Rafael J. Wysocki
2008-11-16T16:24:10Z

[NOTES:
(1) Due to some recent controversies, in future I will only use 'Handled-By'
tags for people who actually submit a patch or provide substantial help to
the reporter (like advising him which commits to revert etc.).
(2) We have almost as many regressions with patches as unresolved ones and
the majority of these patches have not been merged for over two weeks
(for almost three weeks in many cases and for over a _month_ in one case).
IMO, this is insane.]

This message contains a list of some regressions from 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 from 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.

For details, please visit the bug entries and follow the links given in
references.

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 2.6.27,
unresolved as well as resolved, at:

http://bugzilla.kernel.org/show_bug.cgi?id=11808

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

Thanks,
Rafael
