Latest Raspbian kernel upgrade (4.19.118) has changed the I2C management and there is a bug that will prevent your computer from booting.
According to Raspberry developers this will be fixed on next kernel versions but they have not given a date.
If you have not installed the Moitessier HAT app in your OpenPlotter system ignore this and update the kernel normally.
These are our provisional solutions:

There is another issue with 118 kernel: all GPS related messages are filtered out by the kernel module, although everything is enabled in the configuration. There is a patch available for this. Or is it only me experiencing this?
I do not think your problem is related to the kernel, please open a new post and we will see.

For clarification. If I follow step 4 in scenerio 2, I can then run an update of Raspberry Pi OS?
Specifically, after running "4. Install the bug fix: sudo moitessier/scripts/bug_fix_kernel_4.19.118 moitessier/dtbo/i2c-gpio_bug_fix_4.19.118.dtbo". I can then "sudo apt update" and "sudo apt full-upgrade"?
Before I do anything, I want to check. Also, what are the ramifications of this bug fix? Does anything else brake when this is done?
I followed option 2 and my Pi would no longer boot. I edited config.txt as in option 1 and got it to boot, then updated again. With the sudo apt full-upgrade I get this error:

You might try to install the package again.

...and it still will not boot.
I don't know what is going on, but I formatted my SD, put a fresh image of OpenPlotter Moitessier HAT (no update at end of install), installed MCS, Updated all apps, rebooted. All good. I followed option 2 and got the same results as above. Same errors and my Pi will NOT boot.

Thank you. At least I know that I probably didn't to anything wrong.
