Hi,
After updating to 1903 LatencyMon associates ntoskrnl.exe with large latency spikes on the order of ~1,300µs. Same results with KB4497935.
I posted here too as I thought it could be related to the GPU driver:
Others are also reporting similar symptoms. E.g. in some instances this results in noticeable audio clicks/pops.
https://www.reddit.com/r/Windows10/comments/bu34xv/update_1903_high_dpc_latency_issues/
Are you seeing similar results?
Does anyone at Microsoft acknowledge this?
It should be easily reproducible.
Thanks,
Howard
SOLUTION:
KB4505903 seems to have significantly mitigated the ntoskrnl.exe latency spikes for many users.
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
Doesn't seem to be related to audio or ethernet drivers, have tried with realtek audio disabled in the BIOS and with a Yamaha AG03 USB audio interface, ntoskrnl.exe was still causing issues.
Have also tried with the Intel i211-AT ethernet controller disabled in the bios and without, no change.
It's a Windows issue.
If I am not wrong. This issue could be caused by either the audio or LAN drivers.
I'm guessing that the current drivers are not fully compatible with 1903.

Hey, thanks for the help. But I found another solution! On the sysadmin subreddit someone posted a tool to download previous versions directly from Microsoft servers! Now I got the 1803 and 1809, it's gonna be a long day tomorrow but I won't have to deal with these annoying bugs from 1903 at least!
Cheers and good luck everyone!
Oldest one they seem to provide is 1809 if you spoof your brower's user agent (otherwise you can only get 1903). 1809 seems fairly mature at this point so it might be a good alternative to 1803.
