Sorry, running with this patch since a week, but missed to give
feedback.

As others already reported, no regressions here on amd64 also.

your patch - just like Michal's - improves the situation a lot.

Watching videos (HD) fullscreen in a browser without stuttering - the
GUI stays responsive as well.

Thank you both!

I can also confirm this patch makes a HUGE difference in video playback
performance in firefox and minitube on my T400.

This is the first time I can watch videos without stuttering (even in
HD/full screen).

And it seems to improve "GUI responsiveness" in general, too.

Thank you for working on this!

I also don't see regressions on my amd64 - running since 3 days on my

I'm getting the very same error on my Thinkpad T400. (Gregor, you seem
to have quite similar hardware ...)

However, in case it helps, I've also taken pictures of the screen:

I've been watching videos and listening to music with both xine and

resume, checked battery/temperature status, and the system survived a
complete working day. No regressions.

 I know my report is not a benchmark of any kind but I do see a slight
 improvements when running a full GNOME 3 installation.
 ipis never go past 10K where they are regularly around 50K without this
 patch (confirmed with 2 different amd64 boxes).

I can confirm this, too. GNOME 3 generated around 80.000 to over 100.000
ipis, by simply moving the mouse cursor over the menu entries for a few
seconds! The desktop felt sluggish. With this patch, the same
procedure feels less sluggish, and the ipi count dropped down to 9.000 to
15.000.

Further, the time it takes to compile the kernel more than halved from
~10min to 4,27min.

And, the best of all, the first time I'm able to watch html5 embedded
videos smoothly, even in full screen mode.

But not on my amd64 machine, unfortunately. I applied the diff to a clean

Ah, I missed to add: when compiled with -fstack-protector, the kernel
boots just fine.

 The diff below changes GCC's default behavior to -fstack-protector-all
 (i.e., add stack protection code to every function instead of just
 some based on heuristics), but you can still revert to the heuristic
 behavior by passing -fstack-protector on the command line.

[...]

 You can now try building things as usual.

I did a complete `make build` of src and xenocara without problems on
i386. A consecutive complete build worked as well. The system seems
to be running stable so far.
