I have problem to compile any of kernel 4.x kernels for qemu-system-arm architecture vexpress-a9. I am using kernel configuration:
make ARCH=arm CROSS_COMPILE=my-arm-cross-compiler- vexpress_defconfig
When the qemu started, I have for the kernel 4.1.10 and 4.2.3 a black window and a high utilization of a CPU. The same result is for the qemu 2.0.0 in ubuntu 14.04 and for the qemu 184.108.40.206. compiled manually.
When I compiled kernel 3.18.22 in the same way: the same compiler and the same configuration are used, this kernel started in qemu correctly.
