Description
kernel/segments.c gdt_entries_init() causes unpredictable behavior.
Sometimes it seems to work just fine, sometimes the serial output is fine but video is still stuck at BIOS or not updating properly. Sometimes nothing works and serial output stuck at GDT setup start
Expected Behavior
Setup segments and move on.
Additional Info
When it works
qemu-system-i386 -machine q35 -kernel build/kernel_bin -serial stdio
GDT setup start.
Flag.
