Hi Guenter, Sudeep,
It now came down to 'x86/cacheinfo: Move cacheinfo sysfs code to generic infrastructure'[1] as you can see here[2].
The facts are:
- You can't boot on i686 only with more than one CPU core on AMD hardware (x86_64 however works) - Using Ubuntu config[3] it boots but creates an kernel >= 1 GB in size on Manjaro - By reverting 0d55ba4[4] the kernel boots.
So we have to find out what is causing this issue[5].
