2011 13 MBP i5 debug info for apparent hang in main graphics engine

*debug info for apparent hang in main graphics engine *

console is giving me this message and it is affecting my MBP's ability to wake from sleep correctly. I get either a dark screen or scrambled graphics and have to hold the power button to re-boot.

(I do have an external display hooked up to the MBP, this was never an issue with all my past Macbooks.)

macbook Pro 13 i5 8,1, Mac OS X (10.6.6), HP LP2065 S-IPS display, http://dougitdesign.com/blog/

Try running the hardware test to see if there is anything detectable:

Otherwise edit the log file and remove any references to your serial number and paste here as much as possible. Someone might be able to figure out what went wrong.

No hardware problems per that test.

Still having the same issue, does not happen every time, but very often.

Will post log contents in just a bit if no other people are able to chime in on this issue...

this issue only happens when computer is allowed to AUTO-SLEEP. If I manually sleep the comp. it is fine. There are others (at MacRumors) that have the same issue with this new MBP 13...

That might come due to corruption in the Energy Saver or System Preferences plist or cache files. You aren't using any third party system cleanup utilities?

I'm getting the same behavior on auto-sleep. Could this be related to doing a full transfer of all system settings from an older MacBook? I transferred using Migration Assistant from a 13" unibody MacBook 2.0Ghz model A1278.

Is there a single file I can delete to clear Energy Saver settings?

David,
That is possible. Worse consequences have been seen using the Migration Assistant from a PowerPC to an Intel Mac. Try creating another admin account to see if the issue persists there. If it does, then the issue is somewhere in System -> Library or Hard drive -> Library. Unfortunately pinning it down may be harder than a simple erase and install and only selectively recovering that which you need from your two backups.

I also did a system migration (from a 2.13 C2D Macbook 5.2)...

thought this might be an issue, so I did another sys. migration with "machine or computer settings" (whatever it says) UNchecked, and the same behavior with autosleep continues.

I also did delete library/preferences/system configuration/com.apple.PowerManagement.plist, and this did not help.

Just to add my voice to this thread and report that I have the exact same issue with a 15" 2011 MBP.

This too was migrated from a MacBook (2008) but the problem occurred for me before the migration so not sure that's related.

Spent over 2 hrs with AppleCare today and no real progress so going to take it to an Apple store next week and try to get it swapped.

My 15" MBP 15 Core i7 has the same problem. Spoke with AppleCare and tried resetting to power management unit and the PRAM; no improvement. Also tried reinstalling the 10.6.7 'early 2011 macbook pro' update - still no change.

Each attempt at waking from sleep produces a series of the same error messages in Console. Here's the full series:

kernel WaitForStamp: Overflowed waiting for stamp 0x70ed on Main ring: called from
kernel timestamp = 0x70eb
kernel ** Debug info for apparent hang in Main graphics engine **
kernel ring head = 0x00200eb4, wrap count = 0x 1
kernel ring tail = 0x000010e0 ring control = 0x00003801 enabled, auto report disabled, waiting, semaphore not waiting, length = 0x004 4KB pages
kernel timestamps = 0x70eb
kernel Semaphore register values:
kernel VRSYNC: (0x12044) = 0x70eb
kernel BRSYNC: (0x22040) = 0x0
kernel RVSYNC: (0x 2040) = 0x0
kernel BVSYNC: (0x22044) = 0x0
kernel RBSYNC: (0x 2044) = 0x0
kernel VBSYNC: (0x12040) = 0x0
kernel Looks like Main ring is stuck waiting on an event
kernel After attempt to clear wait condition = 0x00003001 no longer waiting
kernel kIPEHR: 0x2000000
kernel kINSTDONE: 0x882fbb
kernel kINSTDONE_1: 0x2308a3f

Re-sleeping and re-waking the machine occasionally lets the screen come back on.

The machine itself is running; I can ssh into it from another computer.

I tried disabling hibernation, too ( http://danwarne.com/how-to-turn-off-slow-sleep-hibernate-mode-on-a-macbook-pro/), with no change.

Anyone with new information on the issue? Going to take it to the Apple Store, I suppose, once I have time...

Well, Apple sent me out a new MBP 15" and after restoring from Time Machine I get the exact same problem. So whilst not exactly 'good news' this does suggest to me this is a software issue, not a hardware one so can (and hopefully will) be fixed at some point in the future.

I don't have time to do a erase & install and re-install all apps etc one by one so it looks like I'll just have to live with this for now. I've turned off dynamic switching and it's all fine so not really a big deal.

Gah - just spent > 20k HKD on a new 15" 8,2 MBP to have exactly this problem on wake.

Like some of the others I also restored from my previous laptop a circa 2007/2008 MBP.

I am experiencing this problem intermittently as well. My MBP is always in closed clamshell mode, connected to a 30" Apple Cinema Display (one at work, one at home) using an Apple Mini-Display Port to Dual-Link DVI adaptor. Sometimes, when going to work or coming home form work, the MBP refuses to wake up after being connected to the monitor. Usually the monitor simply stays black. Sometimes, it shows the screen saver image, but never displays the login prompt. The machine then appears to refuse to go back to sleep. The cooling fan revs up to full-speed and if I disconnect the power chord and let it run for a bit, when I eventually have to power-cycle it, the batter is significantly drained.

I have been working with Apple support for the past couple weeks and have sent in 2 diagnostic reports so far.

In my case, I "hand-migrated" my data from a prior MBP. I could not use Migration Assistant because my account on my prior MBP was a Mobile account associated with an OS X Server LDAP setup. The only "library" files I migrated were those that I needed to get specific apps to work (like Mail, and Safari). I have virtually no non-standard apps installed (Firefox, MySQL 5.5.9, MySQL Workbench, OmniGraffle, MacFamily Tree, LogTen Pro, iWork 2009, Office 2008 are the only that I can find).

Same issue with a 2011 MBP 15" (that we just got as a replacement for an older system that had the same problem). I get the same errors in my console logs. I manually moved files over from the old system, so I didn't move any prefs or settings - just docs, music, videos, etc. - just data was moved to the new system.

That tells me I didn't introduce the issue, as it actually happened before I had a chance to move any files over. It sounds like Apple has replaced a number of machines due to this issue. I had 3 logic boards, a heat sync assembly (or whatever it's called), an Airport card and a optical drive replaced over the 18 months we had the machine. Apple threw in the towel and replaced it with this system and it still locks up.

Until Apple fixes this via a SW update (and it will be a SW update, as I can't imagine this is HW related) I'll be turning Sleep off.

Same problems here, MacBook Pro bought April 2011, 13inch, won't wake up

from sleep, display either blank or corrupted:

WaitForStamp: Overflowed waiting for stamp 0xeb2a69 on Main ring: called from waiting for blt buffer (3D blt)

timestamp = 0xeb2a0f

**** Debug info for apparent hang in Main graphics engine ****

ring head = 0x00000028, wrap count = 0x 0

ring tail = 0x00000930 ring control = 0x00003001 enabled, auto report disabled, not waiting, semaphore not waiting, length = 0x004 4KB pages

timestamps = 0xeb2a0f

Semaphore register values:

VRSYNC: (0x12044) = 0x0

BRSYNC: (0x22040) = 0x0

RVSYNC: (0x 2040) = 0x0

BVSYNC: (0x22044) = 0x0

RBSYNC: (0x 2044) = 0x0

VBSYNC: (0x12040) = 0x0

kIPEHR: 0xff6d6c68

kINSTDONE: 0xfffffffe

kINSTDONE_1: 0xbdbf7fff

I hope Apple fix this via a software update soon. This is the second hang I've had on

Yesterday the same issue happened to my MacBook 13" bought on june 2011.

In my case I was browsing internet and playing music in iTunes when it started to freeze intermittently.

I closed and reopened the lid after waiting some seconds and the issue disappeared without a reboot.

It really looks like a bug at the kernel level (graphic driver?).

I hope that Apple fixes this because it's very serious and annoying.
