Try passing init= option to kernel. See Li. ====================================================================== this is my kenel booting log. i guess 'VFS: Mounted root (ext4 filesystem) readonly on device 179:2.' this log means kernel success mount ext4 file system. But i have no idea what 'devtmpfs: error mounting -2' this log meaning. i think devtmpfs error log meaning something wrong when kernel mount rootfs. and i think that some thing wrong cause kernel panic. is that something wrong at my partition layout or bootargs?
