Subjectusb storage sddr09
Date
Hi,

In the patch fest in the last couple of days usb storage support for sddr09
has broken. I see the following in the log (2.5.43-mm2):

mounting then complains /dev/sda1 is not a valid block device. Also attempting to rmmod
usb-storage gets:

Last time I used the device was around 2.5.40 or so - it worked then, but was
much happier if I left a card in the reader during boot.

Ideas?
