2.6.24-rc7-git4: Reported regressions from 2.6.23

2.6.24-rc7-git4: Reported regressions from 2.6.23

[Rafael J. Wysocki]

[RFC: Would that be useful if I sent regression-fixing patches, CCed to the
appropriate maintainers/lists, along with the reports?]

This message contains a list of some regressions from 2.6.23 reported since
2.6.24-rc1 was released, 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 2.6.23, 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.

For details, please 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 2.6.23,
unresolved as well as resolved, at:

http://bugzilla.kernel.org/show_bug.cgi?id=9243

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

Thanks,

I don't think sending the patches around brings much advantage.

But I always also Cc'ed all submitters, maintainers and all people 
somehow involved with one or more of the regressions.

This sometimes required splitting the regression lists into 5-7 emails 
due to some vger rule of dropping emails with IIRC >= 30 recipients, but 
the required grouping of regressions also had the advantage that you 
often have regressions that might or might not be related grouped and 
discussed together.

And if you want to push people to work on regressions or get fixes 
into Linus' tree spamming their INBOX'es with personal copies of 
regression reports sometimes gets regressions fixed faster...

Perhaps keep the regression report as-is, but for each regression with
a patch follow up with an appropriately CC'd reply to the regression
report.  Similar in concept to the regression report being patch 0/X
or how the -stable series patches are announced?

That's exactly what I'm thinking about. :-)

The reporter has disappeared, so I guess this wasn't a regression
caused by the kernel but some other mistake.
