    Ok happened  to me again, running VLC. I  did Clean reinstall of LIon after having it freez 4 or 5 times, Have watched several videos since with no problem Just now watched a vid with vlc, stopped it hit esc to get out of full screen and FREEZ. Hard restart. Everytime I had some sort of sound Like tapping coming form the optical Out connected speakers, Not always the same sound either. This also happened with Qtime X.

    I alos reported earlier . I had a freeze when i plugged in a sanner by usb, then had one, same usb port , when I plugged in  a printer.

    Never had any siimlar problems until Lion.

    Adobe still don't mention OSX 10.7 but I think by choosing 10.6 (all they give you on their website) and it will download Flash version 10.3 beta for Lion

    Replying to myself...

    My experience:

     

    1. Start Lion, got to YouTube, let a video start, put computer to sleep, run video again:  the whole Mac locks up.
    2. Go to YouTube no-Flash (HTML5) trial:  http://www.youtube.com/html5.
    3. Repeat first step.  Results: No freeze.

     

     

    My suggestion above wasn't a perfect fix.  I had the problem again.  But... I found that not all YouTube videos are available in HTML5, so even if you go to the YouTube no-Flash trial I suggested, you can end up getting Flash content.

     

    I've deleted Flash from my system till there's a fix.

     

    (I know others have reported the problem with other types of video - I haven't seen that.)

    Just to update everyone...

     

    I know that most often, people have been having issues after waking from sleep and playing a youtube video. And that has certainly happened to me on at least 2 occasions (out of 5 - i don't remember what happened during the initial few times)

     

    However, ithe freeze just happened to me again, without involvement of youtube.
    Common thing is still the 'wake from sleep'

     

    This time...

    1. I awoke from sleep

    2. went to a download page "file factory"

    3. after a few seconds, the whole computer froze.

    4. maybe filefactory also uses FLASH? (probably...)

     

    Either way, it's not an isolated youtube problem.

     

    Getting really frustrated as this is becoming a daily occurrence.

     

    *add*  I think once, it also happened with playing video of VLC? (not sure if i awoke from sleep or not)

    Seems Adobe know about it, if you go to do a download of the new flash now it links to known issues for the Mac:  http://kb2.adobe.com/cps/905/cpsid_90508.html#main_Flash_Player

     

    Going to beta to stop it happening.

     

    Bit dissappointed though that flash a plug in could crash the entire system. I thought things in safari were sandboxed now and protected us against this sort of rubbish!

    Same issue, but not with videos.  But Flash may be a culprit.  I have been running Safari with Google Maps or Bing Maps up ...

     

    But this has happend 5 times now, and I don't recall what apps or websites were running with prior freezes.

     

    I do have Flip4Mac and Perian installed, but unsure when they are running (does anyone have information on when these components are used)?

    I'm convinced that it's Flash causing the problems, though the fact that a browser plugin can lock up the system is definitely an Apple problem.

     

    I installed a Flash blocker for Firefox, then re-installed Flash on my iMac (Lion).   Opened Firefox, went to YouTube, and saw, in the video window, an "f" button.  That button is put there by Flash Blocker.  Flash can't run till you hit the button.  I hit the button.   In a few seconds the system locked up except for the useless mouse cursor.

     

    This makes me glad I went with Apple's Aperture over Adobe's Lightroom, but even if Flash is junk it shouldn't be able to take over the system and lock it up.

    Tried Chrome, which has Flash built in.  Flash video in YouTube worked, put iMac to sleep, same video after waking up locked up system.

    +1

     

    Watching videoes in Safari, sometimes make my 2011 27" iMac i5 freeze (still able to move the cursor though...).

     

    Experienced the problem when I started the OS X Lion video on Apple's web page, 5 minutes after I had finished the Lion upgrade. Not what I call a very convincing start!

     

    I have to hard shutdown the computer everytime the problem occur. Never had this problem running SL. Please provide a solution ASAP.

    I experience the same problem too on a new iMac 27, 8GB of ram, 2GB of graphic card, fresh upgrade to lion: after sleep, watching a video on youtube will freeze the system: I have to do an hard reset.

    Same issue with my brand new iMac (i7 Core, 4GB RAM etc etc), I had to manually restart it several times. For somenone that just switched from Windows I am getting disapointed. Something should be done about this.

    FYI ...

     

    I just opened a bug report at http://bugreport.apple.com. They requested more information for further investigation. Threrefore I provided the file that gets produced by the "sysdiagnose" tool.

     

    The kernel.log file shows some GPU Debug information. Not sure if it related to this bug,

    May as well my 2 cents seeing I'm having the same problem.

     

    Skimming through the posts, two things stood out, Flash & Java Runtime.

     

    Came across this known issue for OS 10.7 Lion on Adobe site - Java Runtime needs to be installed manually, otherwise applications may behave inconsistently

     

    http://kb2.adobe.com/cps/905/cpsid_90508.html

     

    Don't know if it will help yet but will keep you posted.
