The DVI monitor (via = HDMI->DVI cable) is soundless. (I've not wanted any sound from the rpi2 = so far and have done nothing to explicitly try to initiate such = activity.) The numbers are in the same range right after booting. The dmesg -a output shows more information about irq17: > bcm283x_dwcotg0: mem = 0x980000-0x99ffff irq 17 on simplebus0 Booting with just the keyboard on usb (no Ethernet cable, no mouse, = etc.) still shows the same range of figures. Then unplugging the = keyboard while systat -vmstat is still displayed does not change the = range either.
