More often i'm getting 'system hangs' (system almost freezes for second and after that is slow for something like 1 minute) with error's like this:

Sep 30 00:32:49 Computer-van-William kernel[0]: ar5212GetPendingInterrupts: fatal error, ISR_RAC=0x8402c ISR_S2_S=0x40010000
Sep 30 00:32:49 Computer-van-William kernel[0]: IOAudioStream[0x2b83100]::clipIfNecessary() - Error: attempting to clip to a position more than one buffer ahead of last clip position (68,2938)->(75,10cc).
Sep 30 00:32:49 Computer-van-William kernel[0]: IOAudioStream[0x2b83100]::clipIfNecessary() - adjusting clipped position to (74,2938)


I get it while using frontrow for example (photo viewing), in iTunes or just random while working with programs.
Using a second screen and using firewire disk (getting it much more often if i attach both, but also occures without).

I am also getting the "ar5212GetPendingInterrupts" error. Only, I am experiencing while playing World of Warcraft and using Ventrilo. I created a thread on Apple's Discussion forum about it:

I also submitted a bug to the OSX @ team @ Apple. Hopefully get to it :)

I believe I am also getting this same issue, though I can't confirm if it is the same exact interrupt at the moment (from memory it is something similar)

I posted about it here.

Edit: It is the same interrupt

Hello,

I have been experiencing an issue with my Macbook Pro for a while now. I have google'd the error I'm getting in my /var/log/system.log whenever this particular issue pops up, and I've found a number of users that are also experiencing it.

What I experience whenever this issue pops up is a sudden drop in FPS in World of Warcraft and a Popping Sound in my headphones. It seems to work itself out over time, but there are times where it will happen repeatedly and I'll reboot and it will seem to go away for a bit. Maybe heat is a factor?

I've compiled a list of forum threads in which people are experiencing this issue, in various scenarios:

I recently took my Macbook in for a service and they found that my fan/logic board was faulty. Since getting those fixed I have not yet experienced any more of the interrupts. I am fairly sure now that it is caused by overheating, though as warranty doesn't cover software work I was not able to get the techs to look at it so I can't confirm that.

If I don't get it again in the next couple of weeks I'm going to say it is caused by excess heat.
