Title:
  grub_drop_alloc called with wrong page count

Status in grub2 package in Ubuntu:
  New

Bug description:
  I have a RISC-V virtual machine with Questing installed which I boot
  via EDK II.

  I additionally installed an upstream 6.16-rc1 kernel.

  Booting with the 6.16-rc1 kernel fails.
  When I afterwards choose the Ubuntu 6.14 kernel for booting this fails too with a message
  "grub_drop_alloc called with wrong page count".

  Something must be wrong in the memory management of GRUB.
