0.1.7, vertical blank sync, and the spinning beach ball of death

  • Has anyone noticed when trying to change the settings for vertical blank sync, that it completely crashes the PC?

    My iMac 24"(late 2007) completely dumps when just selecting any setting. I cannot provide a dump as the PC is rendered useless, and only a hard reset will bring it back.

    Completely fresh install of 0.1.7.

    Also shoutcast still dumps after donwloading then buffering streams...

  • LOL!

    Well needless to say, I havent done it since.
    I dont use XBMC as much on the iMac anymore, since I now run it on a mini.
    Thought I would point it out though, as other may have had the same issue.


  • Ok, HERE (http://pastebin.com/f29b5d186) is xbmc.log

    This is with screen setting on auto, and just merely clicking the arrow up/down to select a different v sync mode.

    There is no question it locks up the whole machine, nothing will function.

    I let it go like that for approx. 20 minutes yesterday, only for a minute today.

    The only way to recover was hard reset(hold power button till machine powered off, then power button again to boot).


  • Just tried changing on the mini with 0.1.6 and it works fine.

    Going to try 0.1.6 again on the iMac and see what happens.


  • Thanks for the log! My guess is that it's a driver issue with the ATI video. My wife has the same model iMac (20"), but she'll kick my ass if I start messing with it. I may have similar video hardware in house shortly, so I'll see if I can reproduce here.

    Have you updated the firmware for the video card?

    Hi elan,

    Everything is up to date as far as anything Apple has released.
    I have installed the leopard graphics update of a month or so ago.
    Other than that, Apple hasn't offered anything for vid card.


  • It reminds me of:

    A: "Doctor, it hurts when I do X"
    Doctor: "Don't do X!"

    :)

  • Ok, must be something specific to the iMac hardware, perhaps the 2600HD vid card?

    0.1.6 does the same, completely locks up the PC.

    Any other place I can check for any type of log that may be saved before the PC dumps?


  • The good news is that you don't have to mess with that setting. It defaults to always enabled, and I don't know of any good reasons to turn it off, unless you like watching tearing video.

  • Ouch, nasty problem.

    The Shoutcast problem is a known issue.

    Just to clarify, are you in full-screen mode? If so, can you try windowed mode and see if the entire Mac is hanging, or just XBMC? If not, and the entire machine hangs, that's a serious problem, and sounds like a driver issue.

    The log should be in /var/tmp/xbmc.log after you reboot.

    Thanks, and I'm sorry to hear about your trouble.

    Ya, I more or less found it by accident. I was just experimenting with settings and noticed that happened.

    Hi elan,

    it originally hung in windowed(auto) mode immediately after a clean install.
    It also hung in fullscreen after I tried it again.

    I will try it again now and then pastebin the log....
