Config: config-xanmod-5.10.txt

[xanmod]

Try using this config: config.txt

[ionutnechita]

I tried with the configuration file sent by you, but it didn't work.

[xanmod]

Before compiling, did you run make clean?

[xanmod]

The packages needed to build the kernel are:

build-essential bc kmod cpio flex libncurses5-dev libelf-dev libssl-dev zstd lz4

https://wiki.debian.org/BuildADebianKernelPackage

[ionutnechita]

Hi,

I try with "make clean" and "apt-get install -y build-essential bc kmod cpio flex libncurses5-dev libelf-dev libssl-dev zstd liblz4-dev", but not working.

I try with vanilla flavor kernel from kernel.org and working correctly with this. Maybe is minor regression in Xanmod 5.10 kernel.

List debian packages installed in docker container: apt-package.txt

[xanmod]

XanMod is based on the latest mainline with no commit rollbacks.

You are downloading the source code from git clone or applying this patchset?

I use a debian bullseye docker based environment (chroot) with gcc-11.

[ionutnechita]

I used 5.10 branch with git clone command for downloading project (source code from git clone). I not used patchset.
