Hi,
Got this intel r1300 dual processor server with 2 Em inerfaces and a lot of usb ports, 2Gb and en Promise Fastrack TX2000
Problem is that when em0 gets an interrupt, it also shows up on the USB controller. top shows the exact same amounts of interrupt at both every time over. Which has a lickelyhood of less than zero.
Is this more common, and if so: what might fix it.

This is a common problem, and unfortunately there hasn't been much movement in fixing it. I'd highly suggest disabling USB in the BIOS if
you don't need it.
Aha, the axe method.... :)
Nope, it is a rack server with little use for USB. A rather nice one with video and USB at the front. But currently we're using the ps/2 kbd interface at the back, where there's also a video interface.
Out of curiosity:
Are the ISR's really shared, or is it more an "optical" problem?
em0 is at irq 30
uhc is at irq 16
The server will be here for at most 1 more week, and is available for tests....
