It's not the firmware per se. It's probably the new dpm code. Do you still
get when dpm is disabled?

Indeed. If I turn off dpm, I can suspend successfully and more or less
successfully resume. But a few seconds after resume my X server dies. May be
related or not. Attaching a dmesg taken after that.
It's strange though that with an older kernel I still get hangs on suspend and
resume even though they do not support dpm at all.
So how can I proceed?

Sounds like this may be a problem independent of dpm. Have you ever had
successful suspend and resume? When you say X crash, do you you mean X hangs?
system hangs? segfault?

I've always (meaning > 5 years) had successful suspend and resume on this
machine. Until I updated the firmware files to test UVD and then dpm. With the
original firmware contained in openSUSE's kernel-firmware-20130114git-1.2.1
package, suspend/resume works just fine. I started having problems immediately
after updating the radeon firmware files from your FTP site. In the meantime,
openSUSE shipped an update to the kernel-firmware package with which I see the
same problems.

> hangs? system hangs? segfault?
I mean the X server terminated unexpectedly and I got thrown back to the login
screen. Other than this message and the part about GPU lockup in the dmesg dump
I posted, I could not find any messages.

--- Comment #6 from nine@detonation.org ---
It seems like I have two independent problems which may explain the confusing
results I got:
* with DPM enabled I get hard locks on suspend and sometimes on resume. After
suspend I have to turn off power manually but it seems like it successfully
writes the suspend image to disk. On resume it sometimes locks with disabled
output, sometimes it works.
* Regardless of DPM enabled or not I get X server crashes within minutes after
a suspend/resume cycle. This happens with kernel 3.11.1 with current firmware.
When I downgrade my kernel-firmware package to 20130114git-1.2.1, this problem
vanishes. But the firmware may be the original cause. With the old firmware I
for example do not have direct rendering or acceleration.
At least I found a logfile giving more information about the X server crash.
Attaching.
Is there anything else I can do to debug these problems?

THe only thing that has changed in the ucode is adding new ucode for UVD and
SMC. If you use the newer firmware package but remove the UVD and/or SMC ucode
images, you should get the same behavior as with the old firmware package.
Since dpm is not enabled by default, I think the problem is probably with UVD.

Indeed! After removing CYPRESS_uvd.bin the X server crashes vanish. Only the
hard locks with dpm remain.

I have the same problem with kernel 3.11.6 on Gentoo Linux (stable) with a
Radeon HD 4650. Hibernation itself works, but shortly after resuming the
machine Xorg crashes with a bus error. Additionally dmesg contains messages
about GPU lockups before or after hibernating. Removing the uvd/smc blobs stops
Xorg from crashing, but disables direct rendering (including XVideo, …). Note
that Xorg does *not* crash after resuming from suspend to RAM.
Downgrading to 3.10 (with the same firmware package) does not solve the
problem, so I’m back to 3.4.67 for now, which works (both hibernate/direct
rendering) for me.

Good news: somewhere between kernel 2.12.1 and 2.13-rc2 the hard lockup on
suspend got fixed! I've suspended several times now without a single lockup. On
resume though I still have lockups about half of the time I tried. This is
without UVD firmware but with active DPM
