It looks like you’ve pasted a PCI device identification string — possibly from a tool like lspci -nn or a driver log — and marked it as patched.
The SMBus (System Management Bus) is used for low-speed system management communications, such as reading temperature sensors, fan speeds, and EEPROM information from RAM modules. Without the correct driver, your system might experience minor stability issues or report missing hardware.
ACPI override – Used to fix sleep, hotplug, or SATA mode issues.
"Patched" suggests a modified driver or firmware override. Here is a detailed story based on that concept.
- Operating system (Linux kernel version, or Hackintosh / BSD)?
- What problem you are solving (e.g., sleep/wake, hotplug, VM passthrough, power management)?
- The actual patch you applied or are looking for (e.g., kernel parameter, ACPI patch, driver source code change)?
DEV_8C22: This designates the specific device as the Intel 8 Series/C220 Series System Management Bus (SMBus) Controller.
