Comment 18 for bug 140713

The gfxboot maintainer has posted a patch that does the same thing in a different way. I've tested the patch and it works as expected.

From Steffen Winterfeldt:

Anyway, ss is already saved, so no need for an extra register. Here is
my version (tested and works on my machine):

--- bincode.asm (revision 650)
+++ bincode.asm (working copy)

   mov ax,pm_seg.prog_d16
   mov ds,ax

- mov eax,ss
+ ; needed for KVM:
+ ; ss:rpl must equal cs:rpl in PM for VT. We can't rely on ss
+ ; maintaining its value after the transition.

+ movzx eax,word [rm_seg.ss]
   and esp,0ffffh
   shl eax,4
   add esp,eax
