I am experiencing similar problems as well: I am running 2.4.3 and
applied your hint below, too.
But still the problem exists for -- I assume -- Network Traffic:
I make use of two 3c59x. When I create a lot of network traffic without
writing to the discs -- therefore my assumption -- some driver write
onto the console:
Flags; bus-master 1, dirty NNNNNNNNNN(M) OOOOOOOOOOO(P)
Every sixteen Transmission. (where Ns, M, Os, and P are some figures).
This occurs only when carrying out bulk transfers -- I am running NPtcp
to test this issue.
Probably, someone knows how to dissable something for the network card
driver -- or for some other stuff the error can be created by -- such
that the error disappears.
Thanks in advance!
