Slow Boot - SMSS is the culprit, need help with the diag

Hello. I've run the Window Performance Recorder / Analyzer. I've narrowed the issue down to something going on during SMSSInit. It's nearly 100s of no activity - CPU and Disk IO appear to be nil, but I can't narrow the issue down. This is a decent laptop with the system on the OE SSD and a second NVME M.2 drive loaded for games. I have a sneaking suspicion that it's something to do with that 2nd drive taking a long time to initialize, but I can't prove it. Once boot is complete the system runs very fast. When I restart or shutdown/restart I get the same delay. I've tried Fast Start / No Fast Start. You can see SMSS.exe start around the 4 second mark and it sits there until the 100 second mark. I've run chkdsk and the DISM tool - no issues found. Drivers are latest/greatest including graphics drivers from nVidia and system drivers from AMD.

Thanks

Thank you. I was able to find several threads related to this specific SYS file. I forced a driver rollback on the AMD CoProcessor and I'm back to normal boot times.
Can you tell me how you got to this particular view in Windows Performance Analyzer? I've looked through many of the info panes, but I can't find this particular thread view.

Hi @geonjay and welcome to Tenforums,

I think your boot delay is caused by the AMD Audio CoProcessor driver !



The Realtek Audio driver make a call to the AMD Audio driver that took 93s to complete!

Try to update all your audio drivers. Also update the Firmwares

Hey, I have a very similar issue and I'd like to know how you got that info, what app did u use?

The tool is Windows performance toolkit
