Also. I took the source available here: http://launchpadlibrarian.net/720006283/linux- source-6.8.0_6.8.0-20.20_all.deb I see that, the above mentioned patch is not applied in this source.

Hello Frank, This issue happened on a P10 Denali LPAR(KVM on PowerVM) I haven't built any custom kernel. Per my chat discussion records with my team, https://cdimage.ubuntu.com/ubuntu-server/daily- live/pending/noble-live-server-ppc64el.iso was the ISO I had used and I had downloaded it around Feb 7-9 time frame. Even with the latest ISO available as on today also this issue is getting recreated. Sure, I don't mind giving a try with ISO from proposed. Could you please point me to the ISO path. I did a search but couldn't find it. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2059237 Title: [Ubuntu-24.04] "array-index-out-of-bounds" error is observed after every reboot Status in The Ubuntu-power-systems project: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: == Comment:- Kowshik Jois B S == ---Problem Description--- Below trace messges are observed in dmesg after every reboot.
