* - [ ] Colors in crash screen are not following the kernel color scheme.
* - [ ] Find a way to add intrinsics.
* - [ ] Rework PSF1 font loader.
* - [ ] The cleanup should be done by a thread (tasking). This is done to avoid a deadlock.
*
* ISSUES:
* - [ ] Kernel stack is smashed when an interrupt occurs. (this bug it occurs when an interrupt like IRQ1 or IRQ12 occurs)
