I'm having the same/similar issue.
In my case, top/master switch is Denali version 16.3.6, and all member switches being added are also Denali version 16.3.6. Trying to configure new 5-switch stack, but some switches are stuck in switch state "INITIALIZING" and others don't even add because they are booting up to ROMMOM switch: prompt.
Started over, plugging in one by one, got up to three total switches connected.
#show switch displays all three, but one is in initializing. There is no console logging indicating the switch is being added to the stack.
Switch#show switch
Switch# Role Mac Address Priority H/W Version Current State
------------------------------------------------------------
*1 Active [omitted] 15 V06 Ready
2 Standby [omitted] 1 V06 Ready
3 Member [omitted] 1 V06 Initializing
#show version does not show the third switch.

Edit: Note - they are all the same license version of lanbase and same model (3850-48U-L)
Does anyone have any experience resolving such an issue?

OK, well I think I solved the problem.
I booted the third switch up by itself, not as part of the stack.
I noticed it had an nvram initialization failure:
% failed to initialize nvram
% attempting to recover from backup
%INIT: waited 0 seconds for NVRAM to be available
*Sep 14 18:38:13.374: %SMART_LIC-6-AGENT_READY: Smart Agent for Licensing is initialized
*Sep 14 18:38:13.948: %IOSXE_RP_NV-3-NV_ACCESS_FAIL: Initial read of NVRAM contents failed
Researched the error code (IOSXE_RP_NV-3-NV_ACCESS_FAIL)
Found in Cisco Bug Search tool for bug of version 16.1.1 (bug CSCux96301)
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCux96301/?rfs=iqvred
A similar bug for 16.6.1 (bug CSCvg33382) was also found with same solution as for 16.1.1 bug.
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvg33382/?rfs=iqvred
WORK AROUND/SOLUTION: I issued a wr mem (or copy run start) on the switch, then powered it down, cabled it to the stack, powered it on and it added to the stack successfully.
*Sep 14 19:30:28.004: %STACKMGR-6-SWITCH_ADDED:Switch 3 R0/0: stack_mgr: Switch 3 has been added to the stack.
*Sep 14 19:30:28.004: %STACKMGR-6-SWITCH_ADDED:Switch 3 R0/0: stack_mgr: Switch 3 has been added to the stack.

I had the same issue on a 3 switch stack. Workaround works!
I just want to add make sure you have software auto-upgrade enable on your stack before adding any other switch.
Thanks!

Hi All,
That's good to know that your issue has been solved, I'm just updating the post for others.
Once the newly joined member is fully booted, you see that a mismatch is detected or any member switch stuck in initialization:
3850-Stack#
show switch
Switch/Stack Mac Address : 0c27.24cf.ab80 - Local Mac Address
Mac persistency wait time: Indefinite
H/W Current
Switch# Role Mac Address Priority Version State
------------------------------------------------------------
*1 Active 0c27.24cf.ab80 14 B0 Ready
2 Standby f41f.c238.a800 13 B0 Ready
3 Member b4e9.b0d3.6600 12 0 V-Mismatch
In Global Configuration mode, enter the software auto-upgrade enable command. This enables the feature for any new switches that join the stack.
3850-Stack(config)
#
software auto-upgrade enable
3850-Stack(config)
#
end
You must reload the newly added switch only; a full stack reload is not necessary. In this case, the newly added switch is switch 3, so the reload slot 3 command is entered.
Tip: The slot mentioned in these commands designates the switch in the stack (slot 1 = switch 1).
3850-Stack#
reload slot 3
Proceed with reload?
[confirm]
Regards,
Tayyab
