Re: Ksoftirqd/0 eating all my CPU while transfer

Dear Gleidson Antônio Henriques,

  I have also solved problems with Ksoftirqd/0. After changing 
hardware this problem disappears/hides.
  May be that my hardware loses interrupts, or I do not know what 
was happen.

It is interesting that Ksoftirqd/0 hanged only in AP mode for me. 
In client mode it worked fine. 
  When ath0 device was put down and up, the problem has been resolved for 
a while (several hours).

regards
   Jara
