UTM crashes when loading Linux kernel 6.17 in Ubuntu 25.10 ARM desktop and Ubuntu 26.04 ARM server on macOS 15.7

Describe the issue
I have 2 VM setup to run Ubuntu 25.10 ARM desktop and Ubuntu 26.04 ARM server. After upgrading them from previous Ubuntu major version, the VM crashes. Starting the OS with older kernel, other than 6.17, there is no crash. Previous Linux kernels such as 6.8 and 6.14 loads just fine. These guest OS are running on Apple Virtualisation framework.

Configuration

• UTM Version: 4.7.4
• macOS Version: 15.7
• Mac Chip: M3 Max
