linux启动时遇到的问题！

island2003

1.mounting /proc filesystem
   creating block devices
   failed to creat /dev/ide/host0/bus0/target0/lun0/disc
   failed to creat /dev/ide/host0/bus0/target0/lun0/part1
   failed to creat /dev/ide/host0/bus0/target0/lun0/part2
   failed to creat /dev/ide/host0/bus0/target0/lun0/part3
   failed to creat /dev/ide/host0/bus0/target0/lun0/part4
   failed to creat /dev/ide/host0/bus0/target0/lun0/part5
creating root device
mkrootdev:mknod failed : 17
  
2.mounting usb filesystem时，提示挂接点/proc/bus/usb不存在.

3.Updating /etc/fstab/ cannot stat /dev/hda5:No such file or directory (其中/dev/hda5是swap分)

这是怎么一回子事啊？？？？
