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)

Description of problem:
Since having upgraded to F16 from F14, I am drowning in messages similar to the one below on the console (corrupting any console output)
[ 1400.353433] sd 4:0:0:0: [sdb] Asking for cache data failed
[ 1400.356601] sd 4:0:0:0: [sdb] Assuming drive cache: write through
accompanied by a message similar to the one in /var/log/messages (gradually filling it up)
[ 1400.351374] sd 4:0:0:0: [sdb] Test WP failed, assume Write Enabled
[ 1400.353433] sd 4:0:0:0: [sdb] Asking for cache data failed
[ 1400.356601] sd 4:0:0:0: [sdb] Assuming drive cache: write through
This machine (a netbook) only has one hard disk. sdb seems to refer to the builtin usb card reader.
Version-Release number of selected component (if applicable): PAE-3.1. 5-6.fc16. i686
kernel-
How reproducible:
100%
Expected results:
The kernel not to raise these warnings/errors, but to work flawlessly (Older kernels did).
I am inclined to believe the kernel is not handling this sdb device properly.
