We discussed this internally and noted that customers often cannot reliably reproduce the VM issue. In such cases, the only evidence available is the dmesg logs captured during the incident. Asking them to re-enable debug options later is not practical, since the problem may not occur again. Similarly, exposing the information via ethtool, devlink, or debugfs is less effective because the data is transient and lost after a reboot. As these messages are printed only once during initialization, and not repeated during runtime or driver load/unload, we decided to keep them at info level to aid troubleshooting without adding noise. - Vennela
