I have tested this scenario with the noble-proposed kernel. I could attach and
detach interfaces successfully. No crash/trace messages found.
Guest Env:
===========
Linux ubuntu 6.8.0-43-generic #43-Ubuntu SMP Fri Aug 2 19:46:18 UTC 2024
ppc64le ppc64le ppc64le GNU/Linux
root@ubuntu:~# cat /boot/config-6.8.0-43-generic | grep PCI_DYNAMIC
# CONFIG_PCI_DYNAMIC_OF_NODES is not set
Before Attaching the Interface:
=================================
root@ubuntu:~# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group
default qlen 1000

2: enp0s1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP

After Attaching the Interface:
=================================
# virsh attach-interface Ubuntu2404 bridge --source virbr0
Interface attached successfully

After Detaching the Interface:
=================================
# virsh detach-interface Ubuntu2404 bridge 52:54:00:96:d9:83
