DE210E problems with interrupts

Hi, when I run dahdi_test, it's show me next picture:

The accuracy is very low Then I watch interrupts:

ok, it's look normal, but:

# dahdi_tools



I disabled all unnecessary devices and optimized BIOS settings, but IRQ still misses. What should I do? Thanks.

hi,
it's not affect only a little irq miss .if it's possible,can you provide ssh to me, i will help you to check it
