This seems to correspond to the display output switching to a<br>
different mode. It is present during u-boot, Tianocore and grub,<br>
however. Is there a way to tell the kernel to not change the mode<br>
so that full control via the serial line can be retained? I tried<br>
"nomodeset" which I think should do this by disabling modesetting,<br>
but it has been ineffective. Is there a way to achieve this?<br>
