I think that the grub2 needs to work for many grub shell commands. But critical error is occurred as follow.Bug scenario is as following.- at the grub menu, press C key. - enter "linux /vmlinuz" command to "grub>" shell - enter above command once more. - grub2 does not response.I traced the code lines. So the grub2 is entered and never ended a loop at the grub_core/lib/relocator.c, free_subchunk function. And I could not skip this loop, because if i skip this loop, the /proc/cmdline is broken.
