I also get the "very bad" message when booting 2.5.25 and 2.5.26, even
if no usb devices are connected. From dmesg:

This happens both with preemtible and non-preemtible kernels. I can
still use a Freecom usb cdrw drive though, so maybe this is not a
problem, even though the message indicates that it is.
I also have a performance problem with the uhci-hcd driver. When
writing data to a CDRW in packet writing mode, usb_stor_freecom_reset
is called quite often, see logs below. This happens in both 2.5.25 and
2.5.26. I tested with the usb-uhci-hcd driver in 2.5.25 (edited the
Makefile) just to rule out kernel changes and other usb changes, but
that driver didn't have this problem. I saw one or two freecom reset
messages though, so it's possible that the new driver just makes an
old problem much more frequent.
