2.6.24-rc1-git4: Reported regressions from 2.6.23

2.6.24-rc1-git4: Reported regressions from 2.6.23

[Rafael J. Wysocki]

This message contains a list of some regressions from 2.6.23 which have been
reported since 2.6.24-rc1 was released and for which there are no fixes in the
mainline that 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.

For details, please follow the links given in references.

As you can see, there is a Bugzilla entry for each of the listed regressions.
I'm the owner of some of these entries, so if you want me to reassign them to
someone else, please let me know.

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.


RE: Regressions from 2.6.22

Unfortunately, I'm unable to follow all of the regressions from 2.6.22 reported
since 2.6.23 was released.  Still, there is the Bugzilla entry at:

http://bugzilla.kernel.org/show_bug.cgi?id=9056

that can be used for tracking them.  If you know of any such regression which
has not been fixed in the mainline yet, please create a Bugzilla entry for it
and link it to Bug #9056 (it's sufficient to mark it as blocking Bug #9056 for
this purpose).


Greetings,
Rafael

2.6.23 did not have pata_acpi. Its also not clear this is a bug in
pata_acpi as opposed to pata_ali which knows about the ALi quirks. The
ACPI and ATA specs sort of disagree here so I'll be trying to fix it
anyway.

OK, but please let me keep that on the list.  It may cause some people to
experience problems that were not present before functionality-wise.

Well, my intention is to list the most recent regressions in these messages.

Your regression is in the bugzilla, is marked as a regression and linked
to the appropriate meta bug entry ...

Well, perhaps I'll be able to send a "post 2.6.22 regressions" message with a
longer list from time to time, but I can't promise that.

I am to understand, from a reply from Herbert Xu, that this issue has
existed a long time, definitely since before 2.6.22, therefore it
doesn't belong on the regression list.

The bug reporter says something that drives me a little batty, which
is probably what got this onto the regression list.  He says "2.6.22
(not sure)" as the most recent kernel where the problem didn't occur.

People should list no version at all if they don't know, otherwise
we'll just get more bogons on the regression list.

I have removed it from the list.

Thanks,

I'm fairly sure that this originates with 2.6.21 as it looks very similar to
http://bugzilla.kernel.org/show_bug.cgi?id=8519
which I filed at that time and which I traced to 8030f54499925d07.

I've never been convinced that that change was correct, but as it now "works
for me" due to changes in the Debian default configuration files, I decided
to not follow up.

Of course, not honoring 'all' is more obviously a bug than not honoring
'default' for existing interfaces.

I've added a comment to #8519.

Hope this helps,
Frans Pop
