I have DISABLED USB support in the bios on my IBM 305 servers. It seems FreeBSD still 'sees' USB. I copied the GENERIC kernel to TEST kernel I removed -all- USB support from the new kernel. I then rebooted and I still see this: ohci0: at device 15.2 on pci0 ohci0: [GIANT-LOCKED] usb0: OHCI version 1.0, legacy support usb0: on ohci0 usb0: USB revision 1.0 uhub0: (0x1166) OHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub0: 2 ports with 2 removable, self powered ... .... Interrupt storm detected on "irq11: ohci0"; throttling interrupt source What can I do to get rid of ALL USB support on this 5.3 system as I dont use it and dont want these 'storms' of interrupts! thanks in advance! -- J.D.
