Hi there,

While building kernel 5.11.1 (source:
https://github.com/Frogging-Family/linux-tkg) I got for the first time this
error:

-----

I am suspecting the upgrade to 2.36.1.
However I admit I have more tests to perform to isolate my theory. I will try
this same build from a VM using 2.36.1 and also another VM using a previous
version, plus I will downgrade to previous version of BNUtils on my main
machine, if the system allows me to, and try to build the kernel again.

I do not know what other information to provide, I am not much knowledgeable
about using build tools, even worse when it comes down to troubleshoot build
errors. :(


Thanks
