For some reason, the keyboard interrupt is causing double fault in the iret instruction on my personal workstation (Ryzen 5 3500x). It does not present on my backup laptop (Intel core 2 duo), nor on virtualbox, qemu, bochs. I used the built in interrupt attribute of gcc to make the ISR.

Does your double fault handler dump any information that can help track down the cause?

My (crappy) double fault handler said the double fault happened in the kernel hlt loop now, in the JMP instruction. Hlt loop code:

while(1) asm("hlt");

nevermind, it's just me forgetting to remove sti's after testing
