Greetings,

With regard to hardware interrupt servicing on 2.2, how are nested
interrupts handled on UP? From reading the code, it appears that they are
possible on x86 (assuming no SA_INTERRUPT), but not on Alpha?

If they are possible, is the depth limited only by memory for a new stack
page..?

thanks,
-bp
