The system then boots fine, I attached the dmesg log. Since the netconsole now also works, I assume some kind of IRQ problem which is strengthened by the fact, that the keyboard didn't work either (for scrolling and searching for problems) without the memory limit option. > OK.

Maybe you can use that to capture the kernel > output? I attached the bootlog with the 512 memory-limit enabled and the xen dmesg. Unfortunately I have to drive 200km to install a serial cable to the system. So if there is an IRQ problem would the serial console really help or would it suffer from the same irq problem?
