I had not seen problems like this while running 4.18.18, but
4.19.5 is <br>
now in Fedora updates-testing and is working for me.<br>

class="gmail_default">Yeah - that example was related to the
flexcop cards, but they made under the hood changes to v4l2
that affected more cards, but not all. What sucks is that
the kernel has very strict rules regarding breaking
userspace, but apparently the multimedia (v4l2) subsections
do not adhere to that policy, so they just fix as they go..
Kind of depressing actually.<br>

<p>Thank you for bringing up this issue. I had the same problem on
one of my machines after upgrading three of them from Fedora 28 to
29. I couldn't figure out what the issue was after removing and
installing the nvidia drivers and myth itself. Based on this
info, I rebooted and selected the 4.18.16-200 kernel and the
playback works now. <br>
</p>
<p>You saved me a lot of time as I was preparing to rebuild the
whole machine this weekend. It looks like the 4.19.5 kernel in
Fedora has the patch. Hopefully that will hit the main updates
soon.<br>
</p>
<p>Thank you!</p>
<p>John<br>
