Intel HD Graphics Blue Screen

Hello

 

I've got an issue with 2 (out of a possible 5 in use so far) - IEI NANO-HM551 boards which use the Intel HD Graphics. I'm running Windows Embedded Standard 2009.

 

The IEI boards have a Core i5 installed and 2GB of RAM. I have some systems using the LVDS port (48bit - 1920x1080 - 3 are setup like this, 2 are ok whilst the 3rd is not). I also have 2 which are running LVDS 48bit - 1920x1080 and simultaneously running the HDMI port - 1920x1020 with the driver setup to run the desktop in Extended mode. One of these is also experiencing the problem.

 

The symptom is: our WPF .NET 4.0 application suddenly stops updating the UI.

 

It's been difficult to trace the problem because it happens at random, usually no less than 19+ hours after the OS and application have been running. In other words, to try and reproduce the problem - either it doesn't happen or will take at least 24 hours. The system running with 2x displays it can happen every few hours or every 24+ hours, unfortunately I don't have the luxury to access this system and use it as a test bed given it's deployed to a remote location. All I can do is remotely reboot it to get the application running again.

 

I've managed to get the problem to occur once in the lab with one of the systems that is connected via LVDS to a single monitor. I tried to poke around so I could hopefully discover what was going on. At this point I tried to see if I could interact with our WPF application and discovered it wasn't responding to input. In-fact, I couldn't open other applications either, except I could get into Task Manager and at that point terminate our application. Upon terminating our application, this resulted in the system blue-screening and rebooting. It happened so quickly, I couldn't see the exception code.

 

I was however luckily enough the blue-screen recorded a dump file which I've since analysed. Here's the output:

THREAD_STUCK_IN_DEVICE_DRIVER_M (100000ea)
The device driver is spinning in an infinite loop, most likely waiting for
hardware to become idle. This usually indicates problem with the hardware
itself or with the device driver programming the hardware incorrectly.
If the kernel debugger is connected and running when watchdog detects a
timeout condition then DbgBreakPoint() will be called instead of KeBugCheckEx()
and detailed message including bugcheck arguments will be printed to the
debugger. This way we can identify an offending thread, set breakpoints in it,
and hit go to return to the spinning code to debug it further. Because
KeBugCheckEx() is not called the .bugcheck directive will not return bugcheck
information in this case. The arguments are already printed out to the kernel
debugger. You can also retrieve them from a global variable via
"dd watchdog!g_WdBugCheckData l5" (use dq on NT64).
On MP machines it is possible to hit a timeout when the spinning thread is
interrupted by hardware interrupt and ISR or DPC routine is running at the time
of the bugcheck (this is because the timeout's work item can be delivered and
handled on the second CPU and the same time). If this is the case you will have
to look deeper at the offending thread's stack (e.g. using dds) to determine
spinning code which caused the timeout to occur.
Arguments:
Arg1: 889c25e8, Pointer to a stuck thread object.  Do .thread then kb on it to find
the hung location.
Arg2: 88c4db68, Pointer to a DEFERRED_WATCHDOG object.
Arg3: f78cecbc, Pointer to offending driver name.
Arg4: 00000001, Number of times "intercepted" bugcheck 0xEA was hit (see notes).

I'm 80% confident the issue is not related to our application because I have systems which are working perfectly fine on the same hardware using the same OS image with the same drivers and they have never had a problem. On the on the other extreme I have a system that's experiencing the issue every few hours and the only way we can resolve it is with a reboot.

 

One system has the problem repeatedly, for this I tried wiping the disk and reinstalled everything again (thinking maybe .NET 4.0 was corrupt) but this only lasted a short while (about 28 hours) before the issue reappeared. Meanwhile the system running next to it - continues to fire away like it should, not skipping a beat.

 

The closest I have come to find so far that has any significance is this article on Microsoft - http://support.microsoft.com/kb/293078 - which indicates it's a driver issue. If this is the case, I don't understand why this wouldn't be a problem (i.e. consistent) across all 5 systems running this same motherboard, same CPU, same RAM, same hard drive as well as the exact same XP Embedded image, same version of .NET and same WPF .NET application. If the drivers were the issue, surely it would be affecting more than 2 of the 5 systems (I have at least 5 more to be built) especially given the identical hardware and software configurations.

 

Intel - are you able to help me resolve this?

 

Thanks

Ben

    Hello Ben,

     

    Thank you for the detailed explaination that you have provided about the issue. Regrettably, we only provide technical support for Desktop Versions of Windows, as embedded versions are not supported in our department.

     

    We do hope that you can obtain assistance on the community from other users with similar configurations.

    I haven't 100% confirmed this yet, but here's what I have found.

     

    The WPF Application has a number of animations.

     

    In order to get those animations to appear smooth, I was utilising an Option of 'BitmapCache' - which causes the Graphics Card to cache the visuals in GPU memory.

     

    Turns out this Cache isn't being flushed and over time the GPU is running out of memory.

     

    Interestingly, the HD Graphics allows up to 1024MB but as soon as it reaches about 950MB - 960MB, it's all over, the OS needs to be restarted.

     

    On my development machine, it uses an nVidia Graphics set and it does flush the cache (albeit the screen blinks similar to when you change resolution).

     

    I've turned off almost all BitmapCaching and the problem has resolved (testing for past 6 hours and counting - so far so good - only 250MB of GPU memory consumed).

     

    Unfortunatly the animations are choppy, but the app is not consuming up all the GPU memory which means it shouldn't crash.

     

    I owe a huge amount of thanks to Pete Brown from Microsoft for his time in helping me find the problem as well as giving me some pointers in my application.

     

    Now it would be nice if Intel could fix the driver so it flushes the GPU cache.

     

    It should be noted - the behaviour of the graphics driver is irrelivant to the OS installed, the issue is unchanged on a full copy of Windows XP Professional (which I ended up needing to install so I could profile the application on the Intel hardware in Visual Studio because VS wouldn't install on Windows Embedded).

     

    Maybe for the next release of the Intel HD Graphics Driver you could get the GPU Cache to flush?
