irq_balancer should not cause interrupts to be shared if they weren't before.
shared interrupts means that all devices sharing an ieq have to check their
registers on each interrupt if the interrupt wasn't for them. This increases
interrupt overhead considerably for those interrupts. How much depends
on the particular devices and how many interrupts they process.
Freezing/hangs is of course a bug.
