[ts-7000] external interrupt is bothered by kupdated

["pakorn_0608" <>]

I'm using TS7400 for catch edge signal at portB4 of EP9302.

The edge signal is sending from some device at rate 2k sampling.

It work well, but, sometimes, the external interrupt is bothered when kupdated 
is running.

I saw on "top" command, kupdates is usage high resource of CPU.

How do i manage kupdated and why interrupt is not response when kupdated is 
running. Is it call another interrupt that have higher priority than 
externalinterrupt?

What i should do on this case? Thanks in advance.
