Yum is in the middle of updating the system, & I think
it's stuck due to these problems. If possible I'd love
to avoid any reboots/restarts etc., so that yum may
complete its job :-(.

I have nothing mounted through usb storage ATM, though
I must have had something earlier today.

Thanks
Hari

Try 2.6.14-rc2-git2, it should be fixed there.

Yes. When I tried to mount/umount usb storage few
times, it appears to work normal under
2.6.14-rc2-git3. I'll keep an eye on usb-storage
throughout 2.6.14-rc*.

I can confirm that the issues I had with all of my USB devices becoming 
unavailable has not been seen. Uptime now over four days, that is WAY 
longer than it took to fail before!
