Well, yes, but will this be _fixed_? :-)  Rebooting the machine every time
I want to download images from my camera is far from a "fix".. but I'll try
the dd thing now.

Would it be possible to add a kernel option to allocate a permanent buffer
for umass?  It would be a kludge, but better than a reboot, IMHO..
