GRUB developers, I just installed GRUB 2.02~beta2-22+deb8u1 from the current Debian distribution. I am using it to boot an _old_ 80486 (squeeze) distribution on a second partition.
Legacy GRUB can load the old squeeze just fine. Current GRUB reboots the computer after attempting to boot the kernel. I did a 'set debug=all' right before the 'linux' and 'initrd' commands. Below is the output. - Matthew Loading Linux 3.19.0 ... script/script.c:65: free 0x3fd9690 script/script.c:65: free 0x3fd96b0 script/script.c:65: free 0x3fd96d0 script/script.c:65: free 0x3fd9460
