+interrupt problem x86_64
+
+Hello.
+I'm studing the x86_64 arch to port colinux to this new architecture.
+
+For who does not know, colinux is a port of linux that runs on windows NATIVELY. Colinux is
+1) a small windows driver
+2) a kernel patched
+3) some windows user-space application that talk with linux kernel (network, console, ...)
+
+I have written the more internal part of colinux, that is the code that switch between windows and linux.
+This is done saving and restore the machine state :
+1) CR3
+2) IDT
+3) registers
+
+The problem I see is that after the switch I see the reboot of my virtual machine.
+I would say that the new IDT and/or CR3 is not flushed.
+My code is written in asm/C so I can follow the code step by step.
+I can say exactly the instruction that is broken.
+
+All my code runs nicely on bochs.
+I don't have an x86_64 real PC.
+
+If someone wants to repair this bug .... I'm here.
+
+Paolo Minazzi
