Hi,

does anyone know if there is a documentation on what is on the various
I2C busses/addresses of a Frame.Work Laptop?

In my case of the FW16 I keep seeing:

...
[6371291.229495] ig4iic1: Warning: NACK for slave address 0x2c
[6379997.956896] ig4iic1: Warning: NACK for slave address 0x2c
[6386165.798471] ig4iic1: Warning: NACK for slave address 0x2c
[6386245.914464] ig4iic1: Warning: NACK for slave address 0x2c
[6390329.197184] ig4iic1: Warning: NACK for slave address 0x2c
...

and I'd like to know what is on each bus, and address.

I did not have this on my initial install of main last year but it
started around my September update if I am not mis-remembering.

/bz
