Hello Christopher,
I confirm that I still have this crash when using the lastest RC version of the
kernel (v3.13 RC3) on Ubuntu Trusty.
Note that this bug has also been reported to DRI DRM/Radeon devs:

Matthieu Baerts, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
Matthieu Baerts, could you please test the latest mainline kernel via
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc3-trusty/ and
advise to the results?

Hello Christopher,
Sorry for the delay.
I'm currently not able to bisect this bug simply because I've not enough free
space on my hard disk...
Maybe I can test a patch or a specific version and used my ppa to compile that
but I don't know if it will help.
Note that it seems I'm not the only

@Christopher: I still have this crash with the upstream kernel version
3.12.0-031200.
It seems that it still crash in 'r600_pcie_gart_tlb_flush'.
Note that I no longer have this crash if I remove this line from

Matthieu Baerts, if you disable your card in BIOS (assuming this is an
option) does this allow you to save power and avoid the crash?

I added

Yes. According to the backtrace, it's due to the Radeon driver (there are some
lines with 'r600_pcie(...)').
I can take a picture but should I open a new bug report?

Matthieu Baerts, it would not be necessary to file a new report at this
time.
Could you please test the latest upstream kernel available (not the daily
folder, but the one all the way at the bottom) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional

@Christopher: I'm now using Ubuntu Trusty but I'm not able to start kernel
3.12, it crashes immediately.
The backtrace is not available in /var/log/kern.log, what can I do more? Do you
want a screenshot of this crash?
