When we use a JFFS2 file system and mount the kernel, the network driver works fine. I have been following the mailing list and could find some issues with NFS on 2.6.37 but I am not too sure whether the kernel crash I am getting is related to that. The driver worked fine on 2.6.32 kernel, but while booting the 2.6.37 kernel I get the following log messages: stmmac: Rx Checksum Offload Engine supported TX Checksum insertion supported IP-Config: Complete: device=eth0, addr=192.168.1.10, mask=255.255.255.0, gw=255.255.255.255, host=192.168.1.10, domain=, nis-domain=(none), bootserver=192.168.1.1, rootserver=192.168.1.1, rootpath= VFS: Unable to mount root fs via NFS, trying floppy.
