Hello Kowshik Jois, thanks for raising our attention on this.
I apologize, but once a Launchpad ticket got closed (for example as Fix
Released), like with LP#2055126, it is no longer actively monitored anymore (by
our team), hence we missed your additional comments.
(I just found your comments, after I explicitly opened it again ...)
In addition I personally didn't recognized LP#2052767, since it wasn't
opened via the Bugzilla-to-Launchpad bridge, hence wasn't marked as
affecting the 'The Ubuntu-power-systems project', which is what we
actively monitor.
But anyway, each problem needs it's own Launchpad entry, so it was correct to
open this one here.
(I'll just mark LP#2052767 as a duplicate of this one, LP#2059237).

So it looks like this happens with a kernel 6.6 (info taken from LP#2052767:
linux-6.6.0 - is this an upstream kernel build that you did by yourself? Since
- afair - we never had a kernel 6.6 in noble/24.04, just a 6.7.)
and with kernel 6.8.0-11 (from the bug description here) - that is the one we
currently have in the daily IOSs.
There is already an updated kernel available from our "-proposed" pocket.
$ rmadison --arch=ppc64el --suite=noble,noble-proposed linux-generic
linux-generic | 6.8.0-11.11+1 | noble | ppc64el
linux-generic | 6.8.0-20.20+1 | noble-proposed | ppc64el <==
Would you mind installing and trying the 6.8.0-20 from proposed, to see if that
(very latest) kernel still shows this 'UBSAN: array-index-out-of-bounds' issue?
