I am running snapgear-3.4.0 with a preemptive 2.6 kernel, on a
montejade-like board (IXP425 CPU).
I get the following error message when I run some apps that access the
ethernet device, e.g. ifconfig:
What version of the AccessLibrary are you using?

Is this a know issue? Is it OK or a real bug that needs sorting out?
(I don't have any experience with the preemptive patch - we've been
using kernel 2.4 till now)
Thanks,
