ASUS X99-E WS / USB 3.1 W10 1903 Latency ntoskrnl.exe
I am getting 2000+ microsecond DPC latency spike measured with LatencyMonitor. The identified source is the ntoskrnl.exe.
This is happening with W10 1903, I don't get this error on the same system using W10 1809.
for troubleshooting to rule out my specific software loads; I did a clean install of 1809 and then previewed 1903 and ran all updates.
The problem this causes for my system is buffer underruns when running audio software/hardware for recording.
I have toggled Hyperthreading, OCing my chip, (always C-States off and Throttling, search off, SYSMain off, etc....) . Have latest nVidia quadro drivers for 1903. Windows updates all chipset drivers, (I can't install Asus drivers as they are older than those provided from Windows 10 updates).
I am curious if this is on anyone's radar here for your systems or if you have had similar issues. Given it is a near on/off correlation from 1809 to 1903 I surmise it is MS code, however working to find a needle in a haystack that says it might be something different that I am just not aware of. Working to avoid paid support via MS until absolutely necessary.
I would be grateful for any advise. Obviously locked down on 1809 for the foreseeable future.
