Hello all,
I have an early 2008 MacBook 2.4GHz Core 2 Duo w/ 4GB of RAM. I upgraded from Snow Leopard to Lion as soon as it came out and have had beach ball/hard lock issues ever since, but only on occasion. I took it to the Genius bar and we figured it was an old preference pane that wasn't Lion compatible, but I uninstalled all of them and I am still getting instability (my machine was rock_solid before upgrading to Lion). I have booted up from the restore partition, repaired my disk and fixed prefs from there, no luck. Cleared out caches with Onyx, no luck.
It seems to have something to do with sound. Getting an instant message on iChat or Adium triggers it sometimes (because of the 'ding' sound), a new email, while playing iTunes, or while listening to audio in a web browser. Symptoms include clicking through the speakers, and when I look at my headphone jack the optical light flashes on and off and the speaker symbol in the menu bar turns grey, like it does when I stream audio via AirTunes, and I get a beach ball in whatever application is the cause. The instability escalates system wide until my mouse cursor starts skipping and I can't do anything at all except force shut down with the power button.
I decided to take a peek in Console and this is what I found:

Things that stick out to me (I know nothing about kernels/troubleshooting issues of this sort):
Kernel Extensions in backtrace:
AppleHDAEngineOutput: bad busy count (255, 1)
com.apple.iokit.IOAudioFamily
com.apple.driver.AppleHDA
Does anyone have any idea what any of this means? Input would be much appreciated. I might just say the hell with it, wipe the drive clean and manually reinstall my applications and data (assuming that a Time Machine restore will just reinstate the driver problem) but of course I'd rather avoid that if there is an easy fix.
Thanks in advance!
