Just my 5 cents: I am working on the imx 35 platform and i am also having
problems with the network setup. I have sent a bugsplat to this list which
occurs in the network setup with 3.2-rt. I suspect that these two errors are
related. Steven Rosted wanted to look after it, but it seems he hasn't until
now.
Best regards
Tim
