* - [?] Rewrite virtual file system. (it's very bad, I don't know how I wrote it this bad)
* - [ ] Colors in crash screen are not following the kernel color scheme.
* - [ ] Find a way to add intrinsics.
* - [ ] Rework PSF1 font loader.
*
* ISSUES:
* - [ ] Kernel stack is smashed when an interrupt occurs. (this bug it occurs when an interrupt like IRQ1 or IRQ12 occurs)
* - [ ] After setting the new stack pointer, the kernel crashes with an invalid opcode.
* - [?] After setting the new stack pointer, the kernel crashes with an invalid opcode.
* - [ ] Somewhere in the kernel, the memory is wrongly freed or memcpy/memset.
* - [ ] GlobalDescriptorTable::SetKernelStack() is not working properly.
* - [ ] Sometimes while the kernel is inside BeforeShutdown(), we end up in a deadlock.
