So, I recognized that the kernel doesn't halt after the "No booting the kernel" message. There are many output messages in the __log_buf variable until it stops at with a "Kernel panic" because the rootfs is not found (but this is the minor problem). Now, I know that the kernel boots but I don't get an output with my Xilinx UartLite module. Are there some kernel modules which must be activated?? Btw. I have used the Linux-2.6-virtex kernel from http://git.secretlab.ca/git/ and another Kernel (2.6.23 from kernel.org) - both with the same result.
