Subject: ub vs. usb-storage

Hi,

Using kernel 2.6.9 bk7 and the UB driver for mass-storage I seem to see
spikes on the load-avg of over 700. There is also times of extreme
responsiveness deficiency.

Using the usb_storage driver seems to fix the problem. Is UB only meant
for low performance situations?

This sounds curious. I'd like to hear more about it. Is there anything
interesting in dmesg?
