with that controller (or at least I don't have an idea what else to try).
Try CCing Heiner Kallweit for ideas about the i801 controller.
Hi,
i am not Heiner Kallweit, but i found something interesting in
commit ba9ad2af7019 ("i2c: i801: Fix I2C Block Read on 8-Series/C220 and later").
Basically, it seems that the i802 i2c controller indeed features a SPD write disable bit
which blocks all writes for slave addresses 0x50-0x57.
Does the i801 i2c controller driver print something like "SPD Write Disable is set" during
boot?
Thanks,
Armin Wolf
