Can an APIC accept an NMI while already handling an NMI? I didn't think they would interrupt one another, but rather, pend until such time as the previous NMI was cleared
The CPU certainly won't (there is a hidden flag that's cleared on IRET which disables NMI; it's possible to re-enable NMI by executing a dummy IRET inside the NMI handler.)
