Whole OS hangs when closing Safari tabs, I have the detailed Console log that mentions "GPU Restart"

    So I've been having this problem ever since installing El Capitan on my Late 2013 15 inch Retina MBP. Nothing like this or similar to this ever happened with any previous version of OS X (all versions of both Mavericks and Yosemite). Currently using 10.11.3, but the issue has happened on .11.0, .11.1 and .11.2 alike.

    Here's exactly what happens each time:

    • I'm usually on battery power (this may matter later for the GPU)
    • I'm watching a YouTube video in Safari (not sure if it's always a YouTube video or if it's just coincidence, but it's suspicious)
    • I close that tab
    • The entire system completely freezes except for mouse movement. Nothing else responds at all whatsoever.
    • The freeze happens after the tab I closed is gone, but before the other tabs have taken its place, so there's an empty gap where the tab used to be
    • After 10-60 seconds, the system unfreezes and everything is back to normal, with anything I pressed during the freeze quickly flashing on the screen (say, if I pressed Cmd+W twenty times in rage, it will at this point close 20 windows).
    • The console will often, but not always, mention a "System Hang Analysis" with the Intel Iris GPU restarting and failing to restart, until it eventually succeeds. My MBP has a dedicated GPU and is set to automatically switch between the dedicated and the integrated one.
    • The console also mentions "Spotlight[318]: XPC connection was invalidated" many times
    Could anyone look through my Console log below and let me know if there is anything meaningful in there? Could my GPU be failing?

    -- Summary of Status for ALL Rings --
    MAIN Ring is hung in a batch buffer <-- ROOT CAUSE!
    MEDIA Ring is idle
    BLT Ring is idle
    VEBOX Ring is idle

    It says something about "MAIN Ring is hung in a batch buffer <-- ROOT CAUSE!" - does this mean something?

    It's super annoying, happens about once a day, I've reported it to Apple and of course there is no response.

    These guys seem to be having a similar issue, though with Yosemite: link
    And another thread for the same issue on El Capitan on the Apple forums: link

    Maybe watching a YouTube video activates one GPU, and closing that tab causes it to switch to the other GPU, but the deactivation is failing over and over again which causes the system to hang until it succeeds. Just speculation.

    It would be great if someone could explain my console log to me!

    Thanks!

    Can you provide anything from the Console log?
    If you check the Console around the time it happened, and just paste in anything that seems relevant, that could be helpful!

    Yes! This happens to me too, several times a day at most. I'd love to hear if you guys managed to find a root cause for this.

    Apple Support has analyzed my logs and says they are seeing a lot of activity with "Adobe Desktop Service" and "Dropbox". They've asked me to quit those and see if the issue persists, so now I'm testing for that.

    Does anyone else have either of those running?
