<p>Hi Jeremy,</p>
<p><br>
</p>
<p>Nothing between the UVD PG patch and the tip of stg-4.7 seems to be that relevant to 480.</p>
<p><br>
</p>
<p>If 8f877a8 is stable best you can do is bisect (shouldn't take long) with cold boots in between. I too run Fedora 24 + GNOME and have good performance with Carrizo, Stoney, FIJI and Tonga (with the 5dw patch reverted) on the tip of stg-4.7. I have yet
to test a polaris asic though...</p>

<div dir="ltr">I apologise if what I said was unclear. When I mean I reverted back to <span style="font-size:12.8px">8f877a8, I mean I did a hard reset to this commit, i.e. reverting all commits/changes after this one. Basically I reverted the following commits: e3bb40f, 32ba038, 689<wbr>2173, 55a9ab5, 4760300, 8ee519<wbr>6, 381c90a, 5ae6bd0, 9a846b4, <wbr>042f89f,
and 78d1842. I just skimmed it last night, so I can't say for sure where the issue is, but I'm assuming it's one of the drm/amdgpu commits, i.e. excluding commits</span><span style="font-size:12.8px">9a846b4, 042f89f, and 78d1842</span><span style="font-size:12.8px">.</span>

<p>If I read this correctly you reverted the commit which enables UVD PG on Tonga? I can't see how that impacts Polaris at all. </p>
<p><br>
</p>
<p>If I had to guess it's a dGPU state issue. I've had on occasion to resort to cold reboots to bisect the kernel because the GPU firmware can get into states that aren't 100% resolved by a warm reboot.</p>

<p>There is a known bad commit which was reverted by Christian which I guess isn't out on fdo yet. <a href="https://cgit.freedesktop.org/~agd5f/linux/commit/?h=amd-staging-4.7&id=6691270952b6909218c520dcc71a342070c96874" class="m_1706033156892082374m_4386376317330016210m_-3510539901589408934OWAAutoLink" id="m_1706033156892082374m_4386376317330016210m_-3510539901589408934LPlnk533633" target="_blank">https://cgit.freedesktop.org/<wbr>~agd5f/linux/commit/?h=amd-sta<wbr>ging-4.7&id=6691270952b6909218<wbr>c520dcc71a342070c96874</a> that

</div>
<div style="text-align:start">I'm currently regularly building and using the amd-staging-4.7 linux branch, which can be found here:</div>

<div style="text-align:start"><a href="https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-4.7" id="m_1706033156892082374m_4386376317330016210m_-3510539901589408934LPlnk449083" target="_blank">https://cgit.freedesktop.org/~<wbr>agd5f/linux/log/?h=amd-staging<wbr>-4.7</a></div>

<div style="text-align:start">It seems that one of the commits pushed on 2016-10-03 broke something, and I just wanted to give the devs a heads up in case no one noticed. I'm guessing it was caused by one of the commits in the range of e3bb40f all the way up
to 78d1842.</div>
<div style="text-align:start"><br>
</div>
<div style="text-align:start">I'm using an RX480, polaris10. The issue seems to have two symptoms:</div>
<div style="text-align:start">- Plymouth (the boot splash screen) seems to get visually corrupted or just blacked out.</div>
<div style="text-align:start">- After login, the screen just remains black until I hard reset.</div>
<div style="text-align:start"><br>
</div>
<div style="text-align:start">Reverting back to 8f877a8 seems to fix it. I'm using Fedora 24 with GNOME. As well, I haven't had time to bisect, but I can do so if desired.</div>
