2.6.25-rc2: Reported regressions from 2.6.24

2.6.25-rc2: Reported regressions from 2.6.24

[Rafael J. Wysocki]

[This is a bit late, for which I'm sorry, but I waited for things to calm down
a bit, to have something less of a moving target.

Now, following an Ingo's advice, the list has been generated directly out of
the Bugzilla entries used for tracking the bugs.  I'm going to release the
script used for generating the list, so that it can be recreated by anyone on
the fly.]

This message contains a list of some regressions from 2.6.24 reported since
2.6.25-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 2.6.24, 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 2.6.24,
unresolved as well as resolved, at:

http://bugzilla.kernel.org/show_bug.cgi?id=9832

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

Thanks,
Rafael

I have already fixed this one, and fix has been already picked by Linus 
from my tree, so you can drop this one. (even the bugzilla is closed 
properly).

The kernel version seems to be a little bit bogus here :)

These two are the same bug. I think we really need 45b503548 reverted in 
mainline.

Looks like this is issue with CONFIG_GROUP_SCHED. Waiting for Peter's 
feedback.

BTW it would be nice to receive CC in the bugzilla, when I have Handled-by 
on that bug :) (but hey, I know that it is difficult to track all the 
persons addressess, when they are not using them consistently).

Thanks a lot Rafael for this regression tracking.

BTW I think it might still be useful to CC everyone involved on these 
reports, even though the bugzillas probably have the correct addressess 
already.

Thanks,

That's a typo :/ Should read 2.6.25-rc1 instead.

Hmm, the script should have noticed that.  I'll need to figure out why it didn't.

In fact, some people don't like to get messages from the Bugzilla and asked me
directly not to put them in the CC lists in there, so I'm a bit cautious ...

Hm, I'd rather avoid sending messages with 100+ addresses in the CC list. :-)

Perhaps I can write a script to send followup messages to everyone involved
for each of the regressions listed, but that will take time (or perhaps someone
could do that for me ;-)).

question: can we please list the last known good version for each entry?
Since these are all regressions (right?) that information ought to be available
and usually helps down in narrowing causes..

This bug is happening here too. I didn´t apply the patch yet (I´ll do it
when I get home), but if cpufreq is disabled, the system powers off
normally.

I´m using Linus´ git tree, commit 1309d4e68497184d2fd87e892ddf14076c2bda98.

Wow! Please delete CONFIG_SYSFS_DEPRECATED and make it always Y, then.

1. Box is running fine.
2. Kernel upgrade -- sysfs layout changes -- box breaks.
3. sysfs people tell everyone to upgrade userspace or turn on shiny new option
4. Some believe this, upgrades userspace. Option is not needed now,
BTW. It's turned off.
5. Several more kernel upgrades were fine.
6. 2.6.25-rc1 comes out and, who would have thought, requires to turn
on that damn
   option again or else box simply doesn't boot.

Why on earth do we have CONFIG_SYSFS_DEPRECATED at all if the only
sane choice for someone who tests new kernels is to always turn it on?

seconded ...

it's insane how inconvenient certain storage systems are to use, and 
people get turned away with NOATBUG. ITISABUG every time user-space 
breaks or the user has to do _anything_ to get the box working as it 
should.

No, user needn't to do anything. Just turn that default y option really to y 
(yes, you are right, the help text of this option is misleading...). It's like 
you turn off old acpi events option and scream that you acpi daemon doesn't work 
for instance. There are many instances of this behaviour in the kernel. And yes, 
many people don't need that option tuyrned on -- I think we need not-y testers 
too, but it might be my personal feeling.

Hi Rafael,

A fix was proposed and accepted at

The bug has been marked as resolved. (You might want to modify your

Suprise, surprise, make oldconfig won't tell you anything about defaults
because you already turned it off moons ago.

> (yes, you are right, the help text of this option is misleading...).

Agree, reference to 2006 is particularly pathetic, given that breakage
happened on recent fedora (sorry, box was reinstalled since then,
I can't recall which fedora exactly).

Indeed, but don't mix types of breakage, please.
You can turn off ACPI or CPU_FREQ or SMP and forget.
You can't turn off SYSFS_DEPRECATED and forget.

> And yes, many people don't need that option tuyrned on --

Wish them luck.

/me goes on thinking about cpufreqfs to eventually turn off SYSFS
completely.

Well, this usually is only obvious for the cases in which the "guilty" commit
has been identified and that information is already provided in the Bugzilla
entries.

I can add a "Caused-By" tag so that it gets listed, if that helps.

Well, my definition of a regression from 2.6.24 is that it happens when someone
takes a .config that worked with 2.6.24, configures the kernel with that,
leaving the defaults for the options he is _asked_ _for_, and the resulting
kernel doesn't work as expected.

Thanks,
Rafael

The rule is that the regressions are listed as long as they are not fixed _in_
_the_ _mainline_ (or not rejected, in some rare cases), in which cases the
Bugzilla entries should be explicitly marked as "closed".

Yes, just tried. It works fine with SMP both enabled or disabled. I´m not
sure if removing that piece of code is the right thing to do though.

yep, and that's how users determine whether "the new kernel works", so

last-known-good SHOULD be obvious. These are regressions right? 
A regression means "version X worked, version Y does not".
If there is no version X, it's not a regression.

Knowing version X is helpful to know how far back to look.
