Well, between the new bios, new firmware, and 3.11.3 kernel (whose
changelog includes a whole mess of radeon-related fixes) something seems
to have fixed this. I haven't had any lock-ups at all in a few days now
(and the only suspend-related bug I see now is #1184262 which is
entirely unrelated).
I actually haven't seen the suspend hang since updating the bios, though
that could still just be dumb luck. I *am* still seeing the lock-ups as
per comment #8, though they don't trigger apport for some reason. I am
currently installing the updated firmware package (bug #1218691 or my
comment #7 on
I have just updated to the latest bios, as indicated by the dmidecode output:
1.0.18

I will post back if/when I reproduce the issue again.

Still happens with latest kernel. I will note (anecdotally) that it
seems to be substantially more likely if I've done something like a
compile to make the system run hot just before I suspend.

Still occurs with rc7 (I filed a dupe and marked it as such, in case the
updated apport trace is useful).
Moving back to "Confirmed" since I have provided all the information I
can think to provide at this point. Joseph, Christopher, please advise
on next steps.

Both -rc4 and -rc2 are substantially worse:
-rc4 freezes hard immediately on boot-up, it never gets past "loading
initial ramdisk". Modesetting never kicks in. Sysrq+reisub does nothing,
I have to kill the power.
-rc2 boots, but freezes hard immediately on suspend (going in, whereas

Skimming the linux git changes since rc6 (on which the current saucy
kernel is based) show a couple of radeon-related fixes, but nothing that
claims to be relevant to my r6xx card. I don't currently have much hope
that rc7 will fix anything when it lands.

Given that, and the fact that 3.11 includes major radeon changes (in the
form of DPM) and the fact that I have a radeon graphics card, I would
put money on a radeon driver regression.

Unfortunately I have not experienced this bug since originally filing it
here (so I have not yet started a bisect). It does not appear to be
reliably reproducable even on the same kernel version.
If I can get it to happen with any regularity I will try bisecting.

Looking at the changelog for the BIOS, there do not appear to be any
related fixes between 1.0.15 and 1.0.18 so I highly doubt the upgrade
will fix the issue (which does not seem consistently reproducable
anyways). I will do it to be sure, but it may take me a while to get
around to it.

This is a regression since the update to kernel 3.11.0 a few days ago.
