fedora crashes playing videos and flash

Blockquote

Hi. My machine halts on occasion when I play videos, either on youtube, or mplayer ( whatever ) .. and it happens also when I play flash games periodically. I can get the machine to crash if I play more than 2 videos at once ( say in different windows).

fedora26, but this was also happening in fedora25. Thus the upgrade.

Since it is a hard stop, there is no entry in journalctl. on When the machine starts up I do see a message from the GPU .. I will put in a comment after rebooting [ 2.803668] radeon 0000:01:00.0: failed VCE resume (-110).

I suspect the GPU may have an issue since the crashes only happen when vids/flash are involved.
