Further investigation into excessive scheduling latency reveals that when switching from X to a virtual terminal and back causes the ps2 mouse (in my case) to be written via aux_write_dev which disables interrupts for about 3 msec. The rtc_interrupt is held off until interrupts are enabled.
This seems like a long time to have interrupts disabled, does anyone know of a safe alternative?
