Hi,
I installed the ubuntu server 12.04 on my EEEBox which do not have CD
driver but only a SD card reader, and I will always get the following
kernel message on my screen continual and repeated:
[ 53.784718] sd 2:0:0:0: [sdb] Test WP failed, assume Write Enabled
[ 53.786833] sd 2:0:0:0: [sdb] Asking for cache data failed
[ 53.786959] sd 2:0:0:0: [sdb] Assuming drive cache: write through
[ 105.496646] sd 2:0:0:0: [sdb] Test WP failed, assume Write Enabled
[ 105.498764] sd 2:0:0:0: [sdb] Asking for cache data failed
[ 105.498889] sd 2:0:0:0: [sdb] Assuming drive cache: write through
............
Anyone know what reason cased this and how to solve this issue? Thanks
Anyother strange two issues I got on my same ubuntu server:
1, when I run "bash" in command, the two shell prompt will print out,
like this(just one Enter pressed after "bash", no more input):
user at rllab:~$ bash
user at rllab:~$
user at rllab:~$
I do not know what case this, it is not a block issue, but I am just
curious why.
2, when I run "sudo -s", I must input password twice to enter root
shell, and I am certain that the passwords which I inputted twice are
correct :
user at rllab:~$ sudo -s
[sudo] password for user:
Sorry, try again.
[sudo] password for user:
root at rllab:~#
Anyone know what happen for this issue? Thanks
