Hi,
Same issue here : I got my MBP 7.1 last July 2010. In December, it started freezing while I was updating to 10.6.5. And the more I rebooted it, the quicker it froze. Nothing moving, no sound. Dropped dead.
So I took it to an Apple Store in Boston, they ran various tests, and they said it was a hardware issue because the computer would freeze even booting from their system (usb hard drive plugged in). Then I took it to an Apple Store in Paris and basically same conclusions. They changed both the hard drive and the logic board, not knowing what was the issue.
Now, we're 6 months later (roughly), and it started freezing again while I was (again!) updating my system with some minor updates. I can’t tell you what it was since it froze and I can't even get it running long enough to look it up now.
The only things I found were some permission issues when trying to repair the disk, and all related to Airport Utility (but then again, maybe there was more to it : it just froze).
And I got quite an interesting screen this morning (first time) :
Panic (CPU 0 caller 0x13c3d38): “pmLock:waited too long, held by1@13c1ee7”@/SourceCache/AppleIntelCPUPowerManagement/...
Debugger called: <panic>
Backtrace (CPU 0), Frame : return address (4 potential args on stack)
Then lots of “0x52af3f78 : something”
Ending with
MacOS version 10K549
Darwin Kernel Version 10.8.0
And then I was asked to restart my computer. And then it froze. I can’t even boot from the install CD to start from scratch because it freezes during the installation. Could that be a logic board issue?
And I’m not that confident in buying a new one if I keep having these issues because that one is only one year old! (but then there’s no way I’m buying a PC so…).
Does anyone has issues of that kind with newer MBP ?
