On a VM with the GCP kernel (where we first identified the problem), I see:
1. The full kernel log from `journalctl --system > kernlog` attached.
The specific suspend section is here:

Thanks Joesph and Catherine's help.
Hi,
I have alreay synced up with Cananical guys offline about this issue.
I can run "suspend/resume" sucessfully on my local server and VM.
And "PM: failed to suspend: error -16" looks like not cause by my
previous virtio patch ( fd27ef6b44be ("virtio-pci: Introduce admin
virtqueue")) which only modified "virtio_device_freeze" about "suspend"
action.
So I have provide the my steps and debug patch to Joesph and Catherine.
I will also sync up the information here, as follow:
I have read the qemu code and find a way to trigger "suspend/resume" on
my setup, and add some debug message in the latest kerenel
My setps are:
1. QEMU cmdline add following
....
-global PIIX4_PM.disable_s3=0 \
-global PIIX4_PM.disable_s4=1 \
....
-netdev type=tap,ifname=tap0,id=hostnet0,script=no,downscript=no \
-device
virtio-net-pci,netdev=hostnet0,id=net0,mac=$SSH_MAC,bus=pci.0,addr=0x3 \
......
2. In the VM, run "systemctl suspend" to PM suspend the VM into memory
3. In qemu hmp shell, run "system_wakeup" to resume the VM again
My VM configuration:
NIC: 1 virtio nic emulated by QEMU
OS: Ubuntu 22.04.4 LTS
kernel: latest kernel, 6.9-rc7: ee5b455b0ada (kernel2/net-next-virito,
kernel2/master, master) Merge tag 'slab-for-6.9-rc7-fixes' of
git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab)
I add some debug message on the latest kernel, and do above steps to
trigger "suspen/resume". Everything of VM is OK, VM could suspend/resume
successfully.
Follwing is the kernel log:

Have a quick glance at the patch it seems it should not damage the
freeze/restore as it should behave as in the past.
But I found something interesting:
1) assumes 1 admin vq which is not what spec said
2) special function for admin virtqueue during freeze/restore, but it
doesn't do anything special than del_vq()
3) lack real users but I guess e.g the destroy_avq() needs to be
synchronized with the one that is using admin virtqueue

Yes, please show us
1) the kernel log here.
2) the features that the device has like
