The latest comment as of this writing indicates that removing iStat fixes the problem.

Great news guys, in my case the problem has been solved completely, just uninstall iStat menus, it seems that this software installed modules in the kernel of OS X, these modules are giving problems after sleep mode.

UNINSTALL ALL I HAVE THIS SOFTWARE AND MODULES AND NO LONGER HAVE MORE FREEZING.

TRY AND SEE.

The "latest" comment is relative. And no, this doesn't fix the problem.

Yup. Same here on 10.7.0. Not related to Flash, happend with QuickTime video too. Lots of GPU warnings/errors in the system log. Waiting for 10.7.1.

I have the Lion installation sitting on my 27 for a week now, I need to wrap up a project before I feel comfortable to backup everything and run it, and in great irony the project involves a ton of video-on-the-browser testing. THANK YOU for linking this on HN, I would never know otherwise.

Does Flash makes all MBP hot or just my older one?

Makes my 2011 MBP as hot as it did on my 2008 MBP.

Flash's ability to hog resources has scaled in line with moores law.

Do laptops running Windows face the same problems with Flash?

yes, but it's not as bad

So, it's not entirely Adobe's fault is it?

(disclaimer: MB Pro, iMac and iPhone owner, not looking to start a flame war or whatever)

I'm certain that Apple has provided the APIs that would be necessary for Flash to use less than 100% CPU, the problem is that Adobe has decided it's not worth their time to make use of them.

Unless you're suggesting it's the user's fault for not running Windows like he should, I'm not sure how you're thinking it's not Adobe's fault.

If the same software performs better on other platforms then the one platform that has the biggest problems should do something as well, that's what I am saying.

It performs better on one other platform. In my experience, Flash is pretty awful anywhere besides Windows.

And I'm not sure what you mean when you say "the one platform that has the biggest problems should do something as well." Apple and many Linux supporters are doing something — they're aggressively pushing HTML5 and related technologies as an alternative to Flash, over which they have no control.

Yup, heats up and hangs after 20 mins of video playback.

I don't own a MBP, but my mac mini (2.5ghz i5) is heating up pretty quickly (about 20-30 degrees warmer while playing a flash video).

Digging through the thread, it seems like the workaround is to disable sleep, and shutdown when you're done using it.

Apple must not even test their operating systems on their own hardware. That or they released it knowing there was a HUGE bug like this. Either way, pathetic. I used to think their company was so great before they started focusing on iDevice sales and computer build quality dropped through the floor.

Same problem here. Has happened a few times when starting to play video but has also happened a few other times. Seems like something with the video card, hopefully Apple can fix it with a driver update.

I don't use iStat.

I guess I will have to work then. Pity I looked forward to a week of TED talks.

For me, 10.7.2 (Beta) solved the problem. Does not seem to be related to Flash, as it used to crash randomly with any type of video, in/out the browser, in Safari, or in Chrom's own etc.

Same here, but introduced an issue with external display sleeping. Still a beta though.

The first generation of 27" iMacs (Snow Leopard) also had a lot of trouble with Flash video playback. An update from Apple fixed this later.

any eta for 10.7.1?

VLC on my MBP (SL & Lion) is completely unable to play 720p MKV files. I don't understand why. I've scoured the Internet and Apple support forums. Seeking within VLC will basically halt the computer. Normal playback will slow the computer down to where it stops responding to user interaction after 20-30 minutes.

Also, all Flash audio has stopped in Lion now, as of a day or two ago. Just don't upgrade to Lion yet, in my opinion.
