I am getting random screen freezes in which the mouse still moves around but the mouse button and keyboard do not work. If youtube is playing the music continues on. Before a freeze everything works fine. It may work for 1 minute or 1 hour after a reboot and a freeze does not seem to depend on what desktop application I am running.
When this happens I always see the following in the log files.
kernel: DMAR: DRHD: handling fault status reg 2 Jan 24 16:41:19 kernel: DMAR: INTR-REMAP: Request device [[00:00.1] fault index 2b INTR-REMAP:[fault reason 38] Blocked an interrupt request due to source-id verification failure kernel: DMAR: INTR-REMAP: Request device [[00:00.0] fault index 27 INTR-REMAP:[fault reason 38] Blocked an interrupt request due to source-id verification failure Jan 24 16:41:20 /usr/libexec/gdm-x-session[2491]: Successfully activated service 'org.gnome.evolution.dataserver.Calendar7' Jan 24 16:41:20 kernel: DMAR: DRHD: handling fault status reg 202 Jan 24 16:41:20 kernel: DMAR: INTR-REMAP: Request device [[00:00.1] fault index 2b INTR-REMAP:[fault reason 38] Blocked an interrupt request due to source-id verification failure
I can ssh in. I need to reboot to get things working again.
Any idea what this means and how to fix it?
The system is new: Dell Precision Tower 7910 Dual Intel Xeon E5-2687W v3 64GB (8x8GB) 1TB SATA 7.2k AMD FirePro W4100 2GB (4 mDP) LSI SAS 3008
I'm using the standard X driver which is listed as RADEON and under system details: Gallium 0.4 on AMD Cape Verde.
Thanks John

You can also hit ALT-F2 to get a command window, and type "r". This restarts gnome-shell. This always works when I see this and doesn't require you to close any windows, log out, or reboot.
I'd love to know why this happens, but it's infrequent enough that I just do the "r" when it does.

ALT-F2 and "r" did not work.

Then although the symptoms are the same, you have a different issue than I do.

If the keyboard is working at all, you should be able to use the magic sysreq keys. http://www.howtogeek.com/119127/use-the-magic-sysrq-key-on-linux-to-fix-froz...
It's possible that there is a complete kernel panic, and nothing is running, so the keyboard and mouse are unavailable. The fact that the mouse pointer moves and music continues to play makes this unlikely. That couldn't happen unless instructions were being processed by the CPU. What if you unplug and plug in the mouse? Does it start working properly?
Did you try Ctrl-Alt-F2 to reach a virtual console? When in X, the virtual consoles are only reachable via the Ctrl-Alt-F2 version. Once you are in a virtual console, you can look at the X logs, examine journalctl -r or check processes that are suspended. You can even kill the X server, and restart it if you have to.
If you get no joy, try a different kernel, or downgrade X to an earlier version. It is likely that either the video driver or the X version is having a race condition, and locking up. I use the radeon driver on an older amd video card and have no issues at all, so it might be that your card is newer and not as well supported.
If all else fails, search at https://bugzilla.redhat.com/ for bugs that have your problem (say 'X freeze' or 'radeon'), and add your comments, and check for workarounds, or open a new bug describing your problem. Open it against X, even though it could be other things.
Ctrl-Alt-F2 does not work but I can ssh into the box. Once there everything looks fine. Log files only really show DMAR: INTR-REMAP problem. I have restarted gnome but it comes back with a screen flicker and very slow mouse and keyboard movements. Only way to recover fully is a reboot.
While playing a youtube video today I had a freeze and I could use the mouse click to start and stop the video but I could do nothing else.
I have tried Ctrl-Alt-SysRq with no luck. Have not tried the other combinations you linked to.
Perhaps the Firepro is not supported with these kernels I've used. I did see a post with it working with kernel 4.3 on Debian unstable.
Thanks for the suggestions. John
