Hi Thomas/Anup
Currently when booting the kernel against next-master(next-20240222)
with Arm64 on Qualcomm boards RB5/DB845C, the kernel is resulting in
boot failures for our CI. I can send the full logs if required. Most
other boards seem to be fine.
A bisect (full log below) identified this patch as introducing the
failure. Bisected it on the tag "next-20240220" at repo
"https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git".
This works fine on Linux v6.8-rc5
Sample log from failure against run on RB5:
