Sorry didn't see your updates. By default flash-kernel installs the kernel with the highest version as the boot kernel. In your case this was 6.11.0-1010-raspi. To override that:
$ sudo flash-kernel --force 6.11.0-1009-raspi -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2099935 Title: PCI initialization failure following kernel panic reboot on Raspberry Pi CM4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2099935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
