Hi,

Can you post your /proc/mounts. I am not sure whether I will find anything,
but curious on this.

Thanks,
Soham

I noticed this happening at regular intervals on my wife's F15 laptop
as well. I don't know what the cause is...

F16: [sdb] Asking for cache data failed

[Ralf Corsepius]

Hi,

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

Does anybody know a workaround/fix to prevent the kernel from issuing 
them rsp. at least to prevent them to pollute the console?

the builtin usb card reader.]
