I've just upgraded my Proxmox Backup Server, running inside a bhyve VM on FreeBSD 15.0-RELEASE, and it now kernel panics as soon as it boots.

EDIT: it's not the virtio driver. This VM has 1G ram. If increased to 2G, it will boot. It seems it's the intramfs unable to decompress. And it's strange.
I've just upgraded my Proxmox Backup Server, running inside a bhyve VM on FreeBSD 15.0-RELEASE, and it now kernel panics as soon as it boots.
Setup:
- Host: FreeBSD 15.0-RELEASE
- Guest Kernel: Linux 7.0
- NIC: virtio-netWorkarounds tested:
- Removing the network device: boots successfully
- Changing the NIC to e1000: boots successfullyThis seems to point to a virtio-net issue with this kernel under bhyve.
Has anyone else noticed this?
