Hi!
It looks that somewhere recently something was broken in ehci again. Trying to write something to msdosfs/ext3fs mounted from external usb2 drive blocks quite qickly. Writing process gets stuck in wdrain state, and disk seems unresponsive -- it just lights up the lamp and does nothing.
Any ideas what to check?
Are you sure its not something specific to your USB stick or the FS ? I am able to write to a couple of different USB sticks here using USB 2.0 no problem on RELENG_5
