Hi Adam,
As you mentioned, I updated the source code and recompiled everything now another issue apperad: "l4linux | Copro10/11 access (FPU), invalid, oops". This failure is solved by disabling CONFIG_VFP, which is already discussed here [1]. I could not forsee the future effect of disabling this attribute in the kernel configuration. The current issue is related to the ramdisk. In the COMPILATION 2 you can see the outputs. I wanted to use ramdisk, but it couldn't work, do you have any idea
