=== 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
</source>
