thank you for your explanation, here is the /etc/fstab of my broken system
# /etc/fstab: static file system information.
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/sda4       /               ext3    errors=remount-ro 0       1
/dev/hda        /media/cdrom0   udf,iso9660 user,noauto     0       0
/dev/scd0       /media/cdrom1   udf,iso9660 user,noauto     0       0
seems no /sys, then where does those error message come from?

yes, there is, it's a 36.5KB executable file.
