>How-To-Repeat:
This is the libvirt domain I use to run it.
Although other virtual machines with different video/storage suffer the same. I haven't be able to isolate the problematic virtio device.
Also, I assume the problem lies in a virtio device, because of the panic trace, but I'm not really sure.

Modified Files:
src/sys/dev/pci: virtio_pci.c
Log Message:
virtio@pci: Nix useless sc_mapped_iosize.
This appears to have been a mistaken attempt to pass the subregion
length through to bus_space_unmap, which doesn't make any sense --
bus_space_subregion does not allocate anything and the resulting
handle must not be passed to bus_space_unmap.
Once we pass the size that was actually returned by pci_mapreg_map to
bus_space_unmap, which matches the size passed internally by
pci_mapreg_map to bus_space_map, sc_mapped_iosize is no longer used
and can be flushed.

Modified Files:
src/sys/dev/pci: virtio_pci.c
Log Message:
virtio@pci: Don't detach on shutdown.
The virtio bus does not keep state in memory that needs to flushed to
persistent storage. Typically DVF_DETACH_SHUTDOWN is only needed by,
e.g., disk drivers to flush disk caches (although really, vfs sync
should do that anyway, so maybe we should just nix the option
altogether).

State-Changed-Why:
Thanks for the report! Can you see if you can still reproduce the
symptom? And, can you also try reproducing the symptom after running
`sysctl -w kern.detachall=1' (each time you boot)?
You can find daily kernel builds for testing here:

with Virtio devices)
Date: Wed, 26 Jun 2024 13:54:33 +0200
Hi! Thank you!
I can't reproduce the problem anymore with kern.detachall=0. But with
kern.detach=1 I get a different panic.
This is what I get with with kern.detachall=0.

Thanks! Looks like we have another bug, and that one's a little more
work to deal with.
Can you try reverting this change?
https://mail-index.netbsd.org/source-changes/2024/06/25/msg151955.html
That change disables access to a code path, but I want to see if I
fixed that code path too.

Hi! Thanks!
I applied the patch and rebuilt. Same results.
This is with kern.detachall = 0

Great, thanks! Unfortunately, I neglected to make it easy to confirm

No need to test with kern.detachall=3D1; that's a separate bug.
