Ok, I applied both patches and rebooted.  Some error messages slightly changed
regarding the USB, some devices were stubborn about accepting addresses
(scanner and mouse still worked, digital cam didn't (as before)).  Network and
sound card both went to IRQ 11 again.  Still PIRQ routing errors.

Attached is dmesg.
