Comment # 1 on bug 944830 from Takashi Iwai

Is this the result with the latest openSUSE-13.2 update kernel?  I guess the
result is same because Tumbleweed has the same issue, but just to be sure.

If yes, try the latest Tumbleweed kernel (on top of the current user-space as
is), also just to make sure.

And if this also fails, please give the output of dmesg after plugging the
problematic USB stick, attach to Bugzilla.
