I have read a few tips on this - but looking for something that works.
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: <OHCI (generic) USB controller> at device 15.2 on pci0
ohci0: [GIANT-LOCKED]
usb0: OHCI version 1.0, legacy support
usb0: <OHCI (generic) USB controller> 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!
If it is not in the kernel see if the module is being loaded. Use kldstat. Did you comment out the usbd in /etc/rc.conf?
