Hello Denys,
I've installed sysstat (good tools!) and the result is very similar
to the one which appears at top, take a look:
13:34:23 CPU %user %nice %sys %iowait %irq %soft %steal %idle intr/s
13:34:24 all 0.00 0.00 2.72 0.00 0.25 12.13 0.99 83.91 16267.33
13:34:24 0 0.00 0.00 21.78 0.00 0.00 0.00 7.92 70.30 40.59
13:34:24 1 0.00 0.00 0.00 0.00 0.99 24.75 0.00 74.26 4025.74

13:34:24 6 0.00 0.00 0.00 0.00 0.00 0.00 0.00 100.00 33.66
13:34:24 7 0.00 0.00 0.00 0.00 0.00 0.00 0.00 100.00 32.67
So, we can assure that the IRQs are not being balanced, and that there
isn't any processor overload.
Thanks!
