"Unknown Power Supply" in ISR4K after upgrade

Hi all,

I upgraded some Cisco ISR4431 from 16.6.4 to 17.6.5, an after that some ISR4K hitted with CSCwf53555.

NAME: "Power Supply Module 1", DESCR: "Unknown Power Supply"
PID: ISR4XXX-PWR-UNKNOWN, VID: , SN:

Then I changed to 17.12.1a because in CSCwf53555 it appear as a fix.

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwf53555.

But, unfortunately, that version has the same results as 17.6.5.

I rollback to 16.6.4, now I can only see the PS0 in "show inventory". With "show platform" the PS1 appears as "Unknown fail, badinput"

#show platform
Chassis type: ISR4431/K9

Slot Type State Insert time (ago)
--------- ------------------- --------------------- -----------------
0 ISR4431/K9 ok 00:04:04
***
P0 PWR-4430-AC ok 00:03:03
P1 Unknown fail, badinput 00:03:03

***

I hope Cisco cloud solve it soon.

Regards.

Jorge
