(This is also being sent to L-K, because someone asked the same question
there.)
It appears that the ehci breakage is caused by a single mal-formed "if"
in ehci-q.c. With this fixed, I am able to access directly-connected
devices on my Ultra30.
There still is a problem, in that I cannot access anything through my
external hub, although it is properly recognized. Connecting a device
to the hub causes no action at all. The hub does work with ohci.
The patch against test6-bk3 is:
