| |
In a lot of cases when there is a kernel panic it obscures on the display the previous problem that caused it and the main reason is that the call stack prints a lot of lines on the display - and there is no way to scroll back up. What led me to make this patch is that I was working on running the kernel on my old computer and when I passed root=/dev/sda to the kernel there was a panic and it could not start init, but since the call stack took almost all the space on the screen, I couldn't see the available partitions the kernel does detects.
After this patch, I could just pass in the new boot parameter I added here and then it would not print the call stack, and I saw the line in which the kernel prints the available partitions.
