<br></div><div>Please upgrade to the latest released versions of mesa, libdrm, xf86-video-intel, your bug is very likely fixed already (since 8.0 is pretty old for gen7).<br><br>Yours, Daniel<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<div><a href="https://bugs.freedesktop.org/show_bug.cgi?id=26345" target="_blank">https://bugs.freedesktop.org/show_bug.cgi?id=26345</a><br>
</div><div><br></div><div>We are running into the same problem with the 3.8.5 kernel (which has the fix mentioned in comment #153 of the bug report) when running a Qt 5 application in Gentoo. At times the entire X session would freeze. The x11-perf tests described in the bug report run without any issues though.</div>
<div><br></div><div>Would you happen to know whether this is because of an issue in the driver that is not currently being addressed by the fix? I have attached the Xorg log, the dmesg output and i915_error_state from a hung session. Please let me know if you need any more info. Thanks in advance!</div>
