<pre>Hi,
I just experienced a GPU hang on a broadwell config (ThinkPad X250).
The dmesg looks like <a href="https://paste.debian.net/167542/">https://paste.debian.net/167542/</a> and the error file is
attached.
I'm running Debian sid, with (custom) kernel 4.0, DDX 2.99.917, libdrm 2.4.58
and mesa 10.4.2. As the log indicates, the I/OMMU is enabled (with
intel_iommu=on). I also have as command line arguments which might be relevant:
i915.enable_ips=0 and intremap_no_x2apic_optout.
If you need anything more, please ask.</pre>
