So I plugged my other Roach1 that's in the lab into where the troubled Roach1 was sitting and started up the netboot. The uImage transferred fine this time, but I got another problem: *VFS: Unable to mount root fs via NFS, trying floppy.* *VFS: Cannot open root device "192.168.40.1:/srv/roach_boot/etch" or unknown-block(2,0)* *Please append a correct "root=" boot option; here are the available partitions:*
