IDA+windbg: mod request has no match for ntkrnlmp.exe

[spokeex]

Connection between windbg extension and ida plugin is made successfully.
Cannot set breakpoints, because "idb isn't enabled".

The only warning/error message I see in IDA, is "[sync] << broker << dispatcher msg: mod request has no match for ntkrnlmp.exe"

I'm attempting to debug a driver that has ntoskrnl imports, so maybe it has something to do with that.

Using IDA home 8.4.

EDIT:
I'm able to start a session with ntoskrnl.exe idb loaded. Then retsync seems to work. I'm still wondering how I can also load the driver Im interested in, into IDA and have that work.
I still have to try https://hex-rays.com/blog/several-files-in-one-idb/.
