Subject: [linux-next20251103] Boot Fail on IBM Power Server

From: Venkat Rao Bagalkote <[email-masked]>
Date: Tue, 4 Nov 2025 11:40:57 +0530

Greetings!!

IBM CI has reported, follwoing boot failure on IBM Power9 server.

I am yet to attempt bisection, meanwhile if its something very obvious, 
please help to fix it.

Attached is the config file.

Console logs:
