[linux-audio-user] Interrupt sharing question

Just a quick question. After installing Redhat 8, I'm a bit concerned by the follwing line in my /proc/interrupts: 10: 476 XT-PIC usb-uhci, usb-uhci, EMU10K1 Aside from the extreme nausea resulting from learning that my sacred MIDI port is being put in the same office as the disgusting mundane usb port, is this a performance issue if I'm not actually using the usb port? I suspect there is a bit of a hit because the interrupt handler now has to poll all the sources, but I maybe not - I understand the principles of interrupt handling but not the specifics of the PCI bus or the linux kernel. So do I need to do something about this, or not? Larry
