I can confirm that this last one
(0001-drm-radeon-kms-fix-panel-scaling-adjusted-mode-setu.patch) fixes
both avivo and legacy.  Please apply.

[Bug 27866] d-r-t crashes at radeon_bo_unref() with dynpm=1

https://bugs.freedesktop.org/show_bug.cgi?id=27866

--- Comment #7 from Aidan Marks <aidan <at> cisco.com> 2010-04-30 16:24:38 PDT ---
yes the crash appears gone thank you, however I am seeing a new issue after the
pull.  every now and again there is screen flicker.  it is extremely fast, if
you blink you will miss it.  one time i noticed momentary display of garbage.

This happens when the reclocking misses the vblank period.  work is ongoing to
avoid that.

output from patch -p1 for all three patches

I tested kernel-2.6.34-rc6 from git. The kernel itself has not fixed the hang.

The patches probably do not apply, because the patched files have changed too
much. I attached the output of 'patch'. However it would be great, if you could
adjust them.

The "add accel parameter patch" applies mostly correct, so the radeon.accel=0

Nouveau / Mesa gets X11 libraries overwritten sometimes

As this has now happened twice in the last two weeks, I thought I'd
write this up.

This morning I came back to my laptop to find it had locked up, even ssh
couldn't gain access to the machine. I rebooted the machine and tried to
start X. X refused to start, so I looked at the logs where it locked up
before I'd even woken up and found the following:

Has some unrelated/old oopses, but anything with 2.6.34-rc5 #34 should be  new
enough ...

[Bug 27904] r300g segfaults on M56GL

https://bugs.freedesktop.org/show_bug.cgi?id=27904

--- Comment #1 from Marek Olšák <maraeo <at> gmail.com> 2010-05-01 16:02:04 PDT ---
Could you please "make realclean" and rebuild the driver? The line numbers from
the backtrace don't make sense, also the "maxtemps" parameter cannot possibly
be 1, it should be either 32 or 128.
