Hi All,

I am afraid that commit 21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler() before i2c_acpi_register_devices()") which is in 5.9 and was also added to 5.8.13 (and possible other stable series releases) causes a regression on some devices including on the Microsoft Surface Go 2 (and possibly also the Go 1) where the system no longer boots.

That commit is also in the following stable releases: 4.9.238 4.14.200 4.19.149 5.4.69 5.8.13

so it would need to fixed in all of those places :)

thanks,
