When I enable CONFIG_USB_OHCI_HCD=y CONFIG_USB_OHCI_HCD_OMAP3=y CONFIG_USB_OHCI_HCD_PLATFORM=y on n900 (I need it on droid4 and want common config), I get oops when attempting to reboot the system. I believe problem is there in v4.17, too. I'll try to build it as a module and debug, but if you have better idea, let me know...
