Possible EFI memory corruption?

Possible EFI memory corruption?

I've been trying to help troubleshoot a problem a user has where grub
appears to hang before booting the kernel when he does not have a USB
device plugged in at boot time.  I had him enable debug messages and
the last one is a malloc in script.c after an append once he executes
the boot command, so it doesn't appear to be making it to the linux
boot function and jumping to the kernel.

I'm not sure where to proceed from here, so perhaps someone else could
be of help?  The original bug report is here:

On EFI debug messages are cut short because of video reconfig/EFI fini.
What is the device in question? Does it when when it's in? Does he have
any USB modules loaded? Normally there shouldn't be any and GRUB
shouldn't be aware of USB at all.
