<pre>(In reply to Mark Janes from <a href="show_bug.cgi?id=99048#c4">comment #4</a>)
<span class="quote">> Assigning to the kernel team, because it appears that OOM can kill a process
> while it holds a lock, generating an unrecoverable error.
>
> To reproduce:
>
> 1) use a device with 1GB RAM
> 2) use Mesa after e9133dd9, when texture sizes were increased
> 3) use piglit before 12b5938, when Ken reduced the memory footprint of
> fbo-maxsize
>
> You should see dmesg errors:
> "Unable to purge GPU memory due lock contention"
>
> Subsequently, other GPU workloads will fail intermittently.</span >
That is not what that means at all.</pre>
