Well, I intentionally asked for revert not bisect. Removing the #ifdef can easily be done by hand if needed and will just need one recompile to make sure. > Crash disappeared whit that little patch. Yes, still I'd like to understand where the BUG came from.

If it fixes a crash, I wouldn't consider it too late. Yet only given we have understood this is a proper fix. Was there a change in using CONFIG_I2C_COMPAT? Is it currently used? Regards, Wolfram
