Ok. Those messages happend just some minutes before the lookup
therefore I thought that they might be in a connection to it.

Sorry, I forgot to tell that I'm using the usb host driver 1.19 on
SDK R1_91 with:
   kernel 2.4.22
   + axis-linux-2_4_22.diff  (applied via running ./install in the SDK dir)
   + ebtables-brnf-3_vs_2.4.22.diff

I've just removed the ebtables-brnf patch, compiled again and
I'm currently re-running the test. If it take again about 2,5 hours
to reach the lookup we've got another 1,5 hours to go...

BTW if it makes a difference here the differences between
my kernelconfig and the axis default:

diff -u kernelconfig.axis kernelconfig.latest | grep "^[\+\-]" | grep -v "^[\+\-]#"
