A quick look at the device map, and that seems to be the PXA2X0_PCMCIA_SLOT1 which is not mapped. You could remove the mkimage and let it try to NFS mount - this is just a test to see if it will boot further. Also with the GUMSTIX and qemu, certain network commands (ntpdate comes to mind) caused page fault in the smc driver. I never investigated. --Mark Tinguely
