Details:
I am booting an x86_64 efi image over tftp on a vmware 10 instance. I'm seeing
an issue in both grub 2.02~beta2 and the latest git when using a gpg public
key with check_signatures enabled. All file operations over tftp (or http)
complete, but grub immediately throws the following error:
alloc magic is broken at <addr>: <value> Aborted.
Press any key to exit.
Pressing a key takes me back to the EFI firmware. I can work around the issue
by disabling check signatures and manually running verify_detached on a file,
but that leaves me having to pull the kernel and initrd twice and nearly
double my boot time. Signature checking from a memdisk does not appear to be
broken.
