MagicAndre1981 Posted June 21, 2012 Author Share Posted June 21, 2012 I just tried running Mediaportal in a window with LatencyMon running and experienced one audio glitch but LatencyMon didn't show any problems at that time. Later I did see an issue in LatencyMon but there wasn't any audio/video glitches that I noticed. This makes it rather hard for me to create the .etl log file at the appropriate time as I won't necessarily have any indication that there has been a latency problem.run this command and do you normal work:xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout -1 && xperf -d DPC_Interrupt.etlafter you got an glitch, go back to the command prompt and stop it. The -MaxFile 256 -FileMode Circular options limit the size to 256MB. So you can run it longer without generating a large file. Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted June 21, 2012 Author Share Posted June 21, 2012 now i think my fan is broke it just intermitly runs its like its runing but not really not sure if its related do u think it the acpi could be the fan being broke or is it just the windows ? The powerplan settings allow you to set a cpu cooler policy. Make sure it is set to "active" and NOT "passive". Link to comment Share on other sites More sharing options...

ChristSavesU2 Posted June 22, 2012 Share Posted June 22, 2012 Hi Andre. In reviewing this thread I see this problem has been going on for a long time. You would think there would be a permanent fix by now. I have been dealing with this issue on and off for almost 2 years. Lately, it is an everyday occurrence. The longer I run the computer the worse it gets. If I let it go on too long I get the BSOD. I have a Gateway SX2800-07 with a core2quad 8300 Intel processor. I have the latest drivers from Gateway, Intel, Realtek, etc... You can download the report.etl from here http://www.willowproperties.net/temp.html. I appreciate all the help you have provided to so many. Any insight you can give me would be great. Thanks, Ron Link to comment Share on other sites More sharing options...

Which USB devices do you use? Does the USB controller share the IRQ with the soundchip?I have a mouse, keyboard, and a printer connected via USB. I have attached the IRQ list. It doesn't appear there are any commonalities between the two.Thanks.1temp.txt Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted June 25, 2012 Author Share Posted June 25, 2012 try to connect the mouse and keyboard to a different USB port. Does this make a difference? Link to comment Share on other sites More sharing options...
ChristSavesU2 Posted June 26, 2012 Share Posted June 26, 2012 try to connect the mouse and keyboard to a different USB port. Does this make a difference?In my previous post, I said I had a USB printer. I forgot that I replaced that with a WiFi printer. So the only two USB devices are the mouse and keyboard. I moved both of them to different USB ports and rebooted the computer. After running all day today the DPC latency is perfect. So far so good. Not sure why moving them to a different port helps but it has so far. I will let you know if it stays that way. Thanks for your help. Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted June 26, 2012 Author Share Posted June 26, 2012 I think this has something to to how the USB ports are handled by the board. But nice to hear you fixed it Link to comment Share on other sites More sharing options...
ChristSavesU2 Posted June 26, 2012 Share Posted June 26, 2012 Unfortunately, the fix didn't last too long. Yesterday it ran all day no problems. Today within 2 hours the DPC latency starting climbing and got to high to use the computer after about 5 hours. I have attached the latest file here http://www.willowproperties.net/temp.html Thanks.

Try to disable this in the BIOS. Link to comment Share on other sites More sharing options...
doveman Posted June 28, 2012 Share Posted June 28, 2012 Hi MagicAndreI caught a glitch tonight with xperf running and have uploaded the zipped .etl to http://www.mediafire.com/?i0joanlus1y4z2i if you'd be good enough to take a look for me.The Mediaportal logs show continuity errors at 21:03:50, so if the .etl contains timestamps hopefully that will help you locate the problem.

MagicAndre1981 Posted June 29, 2012 Author Share Posted June 29, 2012 Hi MagicAndreI caught a glitch tonight with xperf running and have uploaded the zipped .etl to http://www.mediafire.com/?i0joanlus1y4z2i if you'd be good enough to take a look for me.The Mediaportal logs show continuity errors at 21:03:50, so if the .etl contains timestamps hopefully that will help you locate the problem.the etl only contains relative time information not absolute.I can see the high CPU usage spikes by mediaPortal and the ISR/DPC.I can see that the amdppm.sys driver with the function C1Halt causes it. This is the power management driver for your AMD Athlon II X4 630 Processor. This call causes halmacpi.dll!HalpClockInterruptPn CPU usage. This repeats very 100s. The MediaPortal changes the CPU affinity (kernel32.dll!SetThreadAffinityMask) and this seems to cause the spikes. Which powerplan do you use? Do you use the latets BIOS? I've not told you to capture the CPU frequency data xperf -on latency+POWER -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout -1 && xperf -d DPC_Interrupt.etlthis (POWER) captures CPU power stats data.

doveman Posted June 29, 2012 Share Posted June 29, 2012 Thanks for that. I'll try and note what time I start xperf in future then, although perhaps that won't help if it resets the timer when looping the buffer.I use the Balanced profile, normally set to standby after 30 minutes, with the additional "Allow Sleep with Remote Opens" tweak (I'm sure I've probably adjusted some of the other options from default as well though). I'm pretty sure I'm on the latest BIOS but I'll double-check that.I'll do another capture with the latency+POWER command you've posted, thanks.
