note: ,nolock后面不要加rsize=1024,wsize=1024,timeo=15 ，一旦加了以后，console的信息就乱掉了。
而且不能ip=dhcp ，因为我们公司根本就没有dhcp server ，就要 ip=192.168.167.15:192.168.167.168:192.168.167.254:255.255.255.0:omap5912:eth0:off
先擦后写

一般的nfs mount ：
mount -t nfs 192.168.167.150:/work/nfs /nfs -o nolock,rsize=1024,wsize=1024,timeo=15
