--- Comment #10 from Zebediah Figura z.figura12@gmail.com --- I'm not immediately sure I understand how the kernel can be responsible for this. The AMD spec (volume 4 ยง 4.5.3) says "When a null selector is loaded into FS or GS, the contents of the corresponding hidden descriptor register are not altered." Is there a bug in some processors?
