Sadly not much, I can't seem to reproduce :-(

Yanmin, does the wakeup patch I did for oltp help this workload any?

This hits only when sched_compat_yield is set. Sadly, the machine which
did reproduce this for me has gone down. Currently I am away from that
machine for another two weeks. I can try giving it a shot again then.

The regression is bigger with more cpu.

I tested it against 2.6.29-rc9 on 8-core stoakley and 16-core tigerton. volanoMark
chatroom number is default 10.
Basically, comparing with pure 2.6.27-rc9, the patched kernel's result has about 2%
regression. Group scheduling is enabled.

Ok, so that didn't help. Thanks for testing!

Any progress being made with this one? Dave, Oleg did some pretty
nice looking debugging work that indicates it might be a cpufreq
problem. Have you had a chance to look at the comments in the
bugzilla? Or have you been cc'ed on patches for this?

Thanks,
Nick

I'm not convinced that the original report wasn't hardware related.
We had taken a machine check exception already, which shows that something
isn't quite right.  MCEs happening under high load are usually a sign
of thermal/power problems of some sort.

Oleg's comments may still hold true, independant of the report.
I've added Venki to the Cc: as he's recently rewritten considerable
amounts of the ondemand governor (though the workqueue mechanics
are pretty much the same).

Dave, is your CPU2 getting stuck in calibrate_delay? Can you still
reproduce the bug? What if you boot the kernel with lpj=<something sane
like 2666785> in order to skip the calibrate_delay code?

If that helps, can you try adding some printks to narrow down where it
is getting stuck?

This is going to sound strange, but I've forgotten which box that was.
I'm due to reinstall all my test boxes now that the next Fedora beta
has come out anyway, so I'll hopefully figure out by the end of the week :)

That does sound strange ;) But I can't believe that! It would be really
interesting if it was stuck in calibrate_delay, but maybe the backtrace
is just messed up...

If you do manage to reproduce it, I would be quite interested. Otherwise,
I think we can say it's not a showstopper for 2.6.27.

Ok, this can be closed out. 2.6.27 seems to work fine on all the
quad core machines I have in my cube.

the patch is not the actual fix for it. It is just a band aid. As you
confirmed, the double free patch fixes it. See my pull request, but it
didn't make it into Linus' tree yet.

I know, I didn't close this entry just because the fix is not yet in the Linus'

The structural patch for this from Bjorn got NACKed. AFAIK we're still 
waiting for someone (Bjorn?) to decide whether to go with a simpler patch 
from Rene for .27 and to push that.

For me it was possible to work around the issue by changing a BIOS 
setting, but I expect it will still affect others with similar BIOS 
behavior.

As I wrote (and you copied to the bugzilla), this looks a bitflip in
one of the ptes... But no harm in waiting for the reporter to confirm
or disprove before we strike it off the list :)

The problem is actually worse than this description suggests. I updated
the bugzilla entry now.

The new smp_call_function() that is called from panic is quite unsuitable
for this task:
- It allocates memory (not a good idea in panic0
- It complains about interrupt off
- This whole thing breaks at least machine checks

Why doesn't it use something like nmi_shootdown_cpus on panic rather than
the (I guess less reliable and longer latency) smp_send_stop?

Re: [Bug #11569] Don't complain about disabled irqs when the system has paniced

[Andi Kleen]

> Why doesn't it use something like nmi_shootdown_cpus on panic rather than

There are unfortunately a couple of BIOS around that hang randomly when
NMIs are used (e.g. common problem on ThinkPads). That broke the neck
of the NMI watchdog too.

But yes if we had some way to distingush these broken systems from
sane ones NMI would be the way to go in panic.

This is unlikely a 2.6.27 regression.
It's a bug to be fixed, though.

I have not been able to reproduce this recently. I also don't think it's 
really worth tracking this as a regression as there's still a lot of 
uncertainty as to what the cause is.

Just for the reference, this one regresses from the 2.6.23. Particular
2.6.26-27 part can be partially fixed by disabling TSO/GSO, since tbench
workload issues quite small packets, and system has no time to
incorporate them into particulary big TSO/GSO frame to get advantage of
this technology. The most noticeble perfromance drop was between 23 and
24 kernels. I work on this issue.

This one is different, but any other benchmark related to network over
loopback (and in some case over other media) performance degradation
should be very likely handled by the above case.

Still, tbench results from 2.6.26 are better than from 2.6.27-rc.
That's why it's still on the list, but if you think that's not relevant, please
let me know and I'll drop it.

Note that 2.6.27 beats 2.6.26 by 30% with bulk traffic over
loopback as opposed to the small packets sent by tbench where
I saw a 5% drop in performance on my machine.

So I'm not sure whether this should really be classified as
a regression if we limit ourselves to the changes between 26
and 27.

The changes prior to 26 seem to be more significant.

Chyeers,

Yes, that's the point, TSO over loopback for big packets or workload
where there packets can be easily combined into big one results in a
fair performance improvement, but for small packets it regresses about
5-10 %. And yes, there are yet unresolved changes which caused bigger
performance degradation.

I meant it continuously regresses from .23 including 26-27 timeframe.
There were at least two changes in 26-27 which caused tbench regression
in this particular time interval. One of them enabled TSO over loopback
by default, so one can turn it off via ethtools or this patch:
http://marc.info/?l=linux-netdev&m=122263663631600&w=2

another (hopefully) one I'm trying to find out, which is a bit complex
and slow, since e1000 driver changes in the middle of the 26-27
timeframe does not allow my testing machines to boot.

So, there is a regression (partially resolved), but it is only part of
the problem.

Yes, it should remain since it happened recently on 2.6.27-rc8-git6.
Again with blocksize = 1KB.

I don't see any action from the reiserfs developers about trying
to fix this.  Maybe I shouldn't bother testing this.

When the file system is mounted, the module count is incremented. You
can't remove the module underneath a live file system.

2.6.28-rc1-git1: Reported regressions 2.6.26 -> 2.6.27

[Rafael J. Wysocki]

[Here's something new, a list of regressions introduced between 2.6.26 and
2.6.27.  We haven't fixed all of them yet and they're still being reported.
Also, they need to be fixed as well as those introduced later (although they
may be considered as "less important").

Quite frankly, I don't know how this is going to work out, but I thought
it's worth trying.  Enjoy! ;-)]

This message contains a list of some regressions introduced between 2.6.26 and
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 introduced between 2.6.26
and 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.
