What "running with interrupts" ? :-) Are you talking specifically about
suspend/resume ? In this case, normal devices also provide irq_off
variants of suspend/resume.

In some areas, those semantics are even a problem for sysdevs. For
example, it's been a pain in the neck for cpufreq on powermac not to be
able to schedule in its suspend routine. Among others...

Cheers,
Ben.
