80860f14 !new!: Acpi

To resolve this, one may need to resort to manually extracting drivers from a newer Intel Chipset Driver package or rely on driver update tools, though this can be a frustrating and uncertain process.

Fresh installations of Windows (especially Windows 10/11 without manufacturer recovery media) lack the proprietary Intel Serial IO drivers. Windows Update may find them eventually, but manual installation is faster.

: Many devices using this controller have a 64-bit CPU but a 32-bit UEFI firmware , which often requires a specific bootia32.efi file to boot Linux installers correctly. Device Examples This controller is commonly found in: Intel Compute Sticks (First Generation). Acpi 80860f14

Note: The Linux kernel often maps 80860F14 to the dw_i2c (DesignWare I2C) driver via the i2c-designware-platform driver.

If you encounter this device in an unknown state, do not panic. Install the Intel Serial IO driver, reboot, and watch the yellow exclamation mark vanish—replaced by a fully functional peripheral bus. To resolve this, one may need to resort

Troubleshooting ACPI 80860F14: Fixing Storage and WiFi on Intel Bay Trail Devices

The identifier ACPI\80860F14 refers to the Intel SD Host Controller : Many devices using this controller have a

The 80860F14 controller is specifically found on Intel's low-power System-on-Chip (SoC) platforms from the 2013-2016 era, namely and the later Cherry Trail . These chips were designed for:

For developers and tinkerers, the most reliable fix is to replace the broken ACPI table. Using tools like iasl (Intel ASL compiler) and acpidump , you can:

Thus, the kernel sees 80860F14 , initializes the DSP, but then fails to find the codec. This results in the dreaded "failed to add I2C device" error.
