2.6.39 - crash when plugging in a usb memory stick

[Chris Clayton]

Hi,

I've just had the following crash after plugging in a usb memory stick. Some
diagnostic output may be missing because it was scrolled off screen by a
subsequent oops, which I have assumed was induced by this crash and not,
therefore, copied down. Also, I skipped writing down the modules linked because
it's a long list, but there are no out-of-tree modules of any kind and the
kernel was not tainted (until after this crash).

I've been using 2.6.39 since the day it was released, plus -rc version since
rc2 and this is the first crash I have experienced. Consequently, recreating
the crash might not be possible. Nevertheless, let me know if there's any way I
can help to fix this.
