On 5.2-RC FreeBSD 5.2-RC #2: Thu Dec 11 19:52:34 GMT 2003
(cvsupped a few hours before) I seem to get interrupt routing
problem where interrupts that belong to the gigabit ethernet
interfaces get also delivered to uhci1;
There is nothing connected to the USB connectors.
Advice how to debug further appreciated. As a workaround I´m just
dropping usb support from the kernel.
