I 'm trying to send an IPI to myself.
Writing to APIC at position 0x310 and 0x300 succeeds (the interrupt is sent), but only once.
Next write does nothing, until I restart.
Any suggestions?

Probably because the interrupt handler isn't doing something it should do allow another IPI to be sent. – Ross Ridge May 17 '15 at 22:09

What sort of action should be taken then? – Michael Chourdakis May 18 '15 at 04:57

I found it.
I should write to the EOI register.
; Write it to 0xB0 (EOI)
MOV EDI,[DS:LocalApic]
ADD EDI,0xB0
MOV dword [FS:EDI],0
