Hi everyone,
I am experiencing a persistent black screen after trying to resume from suspend on a dGPU-only laptop (AMD Ryzen 7 7435HS + NVIDIA RTX 4060 Mobile) running CachyOS. Since the Ryzen 7435HS lacks an iGPU, the system relies entirely on the discrete RTX 4060.
Upon attempting to wake the laptop up, the screen remains completely blank and unresponsive, requiring a hard reboot.
Looking at the dmesg logs from the failed boot, it appears the open kernel module is failing to communicate with the Lenovo SBIOS (BIOS Version: PQCN27WW) regarding the platform power states:

Is this a known regression or incompatibility in the 610 series driver regarding ACPI/SBIOS PlatformRequestHandler routing on dGPU-only Lenovo laptops? Any help or temporary workaround would be greatly appreciated.
Thanks
