macbook 6,2, mountain lion, kernel panics, reboots since gfxcardstatus 2.3

[glaszig]

anyone else experiencing this occasionally?
gcs is now completely useless for me.
it once worked great (even with anytime-switching) on snow leopard.

[codykrieger]

This is a problem with the com.apple.NVDAResman kernel extension, not a gfxCardStatus issue. I suggest uploading this backtrace and filing a bug report at http://bugreport.apple.com.

[glaszig]

can we leave this open for while? i'd like to know if others are having problems of this kind.

[codykrieger]

This is a common problem on 2010 machines, so others are definitely experiencing this problem. People have actually been using gfxCardStatus in an attempt to avoid hitting this panic. This is related to the black screen issues that these machines had, among other things, because at some level it boils down to the fact that the logic boards in all of these machines are faulty.

If you haven't already had it replaced, I'd get in touch with AppleCare: http://support.apple.com/kb/TS4088

[glaszig]

i know of this kb.

but i DID NOT have such massive problems BEFORE using gcs and mountain lion and haven't got the logic board replaced.
so, logic implies that something significantly changed on the software-side.

as for letting apple replace the logic board: i procrastinate since i'd need to buy another macbook to be able to continue to work while it is away.

[codykrieger]

That's all well and good, but many, many people have been hitting similar crashes since day one of using their machines, as far back as Lion and even Snow Leopard. It's possible that gfxCardStatus "agitates" the machine a bit more, but it is far from being the root cause of this issue.

[glaszig]

sure. people are reporting that even trying to fix the root cause did not solve their problem.
nevermind.

regarding your point of a bug in com.apple.NVDAResman:

it appears there's unpredictable behavior of chips on the logic board but do you think this is catchable/fixable with algorithm in com.apple.NVDAResman?

if there's a hardware-based reason (which, obviously, apple is aware of), i guess there is no point in filing a radar because they'll throw their hands up anyway.

[codykrieger]

I honestly don't know enough about how NVDAResman works, or even what it's responsible for, to answer that question.

[glaszig]

just to let you know: got the logic board replaced 2 (!) times and the crashes are gone.
the apple hardware test at the repair shop immediatly detected faulty video hardware.
the first replacement had an issue with the external display not being de-detected/deactivated after unplug. very weird. the guys said i was the first one having such.
i had to press them to replace that bloody crap a second time and -- voila -- it works.

approx. 1000€ worth of hardware in the trash just because nvidia is too dumb to produce working silicon.

now i'm waiting for #107 to get merged. and a new release.
