[Bug 925760] Re: Constant warnings from the kernel: Test WP failed, assume Write Enabled
Well it did work until I rebooted. The successful solution was to use
"sudo gedit /etc/rc.local" and insert the following commnands before the
last line which contains "exit 0":
rmmod ums_realtek
modprobe ums_realtek ss_en=0
Note "sudo" prefix isn't needed because rc.local runs with root
privileges at startup.

Bug description:
I have this problem with this Laptop Acer 5735-4624, when I change to
a TTY (Ctrl+Alt+F1..) I got this message everytime
Feb 2 17:07:12 telintel26 kernel: [33802.064779] sd 4:0:0:0: [sdb] Test WP failed, assume Write Enabled
Feb 2 17:07:12 telintel26 kernel: [33802.067026] sd 4:0:0:0: [sdb] Asking for cache data failed
Feb 2 17:07:12 telintel26 kernel: [33802.067034] sd 4:0:0:0: [sdb] Assuming drive cache: write through
This are just warnings, because all seems to work OK but are really
nasty messages because appear every time even if you are running
another program (example: top)
