Just one question about dom0's command line.

The original CONFIG_CMDLINE from linux-chrome git repo is "root=/dev/nfs
rw nfsroot=192.168.0.10:/media/opt/cramfs console=ttySAC2,115200
ip=192.168.0.20:192.168.0.10:192.168.0.1:255.255.255.0:test::off
init=/linuxrc". Since I didn't have the same rootfs environment, I
changed it to "console=ttySAC2,115200 text debug verbose earlyprintk
root=/dev/mmcblk1p3 rootwait rw init=/bin/bash". Also, I've tried the
""console=tty text debug verbose earlyprintk root=/dev/mmcblk1p3
rootwait rw", which is the parameters used as host kernel's. None of
them affects the phenomenon I posted on last mail.

And I'm also curious about how you boot the chromeroot using a nfs
rootfs, since there is only wifi connection on it.

Any ideas?
