this looks like at a minimum the apparmor profile needs to be updated.
This needs to be done before any other kernel work. Adding an apparmor
task
lsblk trace shows
openat(AT_FDCWD, "/sys/block/sr0/hidden", O_RDONLY|O_CLOEXEC) = -1 EACCES
(Permission denied)
openat(AT_FDCWD, "/sys/block/sr0/dev", O_RDONLY|O_CLOEXEC) = -1 EACCES
(Permission denied)
openat(AT_FDCWD, "/sys/block/sd0/hidden", O_RDONLY|O_CLOEXEC) = -1 EACCES
(Permission denied)
openat(AT_FDCWD, "/sys/block/sd0/dev", O_RDONLY|O_CLOEXEC) = -1 EACCES
(Permission denied)
which match up with the kernel denials

Deployment fails on Power9 and Power10 nodes when trying with Ubuntu
25.04/Plucky Puffin

Looking its console, it seems deployment has finished quickly:
```

but either way MAAS deployment fails.
MAAS version: 3.5.2
Additional context:
a) I'm able to deploy the same system, via MAAS, when trying with
Jammy/Noble/Oracular
b) Also able to deploy with Plucky Puffin .ISO image (also on the same system
- P10rain-LPAR09).
