I was able to attach to an interrupt using a task entry. This code worked
with the Verdix Ada-83 cross compiler running in SUNOS 4.1.4 with a target of
a VME 68040 processor. Hopefully it will work for you.

clock_interrupt_vector : constant := 16#44#;
task timer_tick is
entry start;
entry tick_isr;
for tick_isr use at SYSTEM.address'ref( clock_interrupt_vector );
pragma passive( interrupt, 16#0700# );
end timer_tick;
