=== I'm receiving a General Protection Fault interrupt immediately after returning from my first interrupt === |

After initializing the gdt with the lgdt command, make sure that you are performing a long jump. For example: |
|||
<source lang="asm"> |
|||
init_gdt: |
|||
lgdt [gdt_table] |
|||
jmp 0x08:longjmp_after_gdt |
|||
longjmp_after_gdt: |
|||
; Do something like repoint segment registers next |
