--- Comment #16 from Hans Petter Selasky <hsela...@freebsd.org> ---
Hi,
ehci_get_port_speed_portsc() should not be in use on amd64. Either the stack is
corrupt or this indicates a problem with the CPU or some registers have been
clobbered.
--HPS
sys/dev/usb/controller/ehci_ixp4xx.c: sc->sc_vendor_get_port_speed =
ehci_get_port_speed_portsc;
sys/dev/usb/controller/ehci_imx.c: esc->sc_vendor_get_port_speed =
ehci_get_port_speed_portsc;
sys/dev/usb/controller/ehci.c:ehci_get_port_speed_portsc(struct ehci_softc *sc,
uint16_t index)
sys/dev/usb/controller/ehci_mv.c: sc->sc_vendor_get_port_speed =
ehci_get_port_speed_portsc;
sys/dev/usb/controller/ehci.h:uint16_t ehci_get_port_speed_portsc(struct
ehci_softc *sc, uint16_t index);
cpufunc.h (amd64):218
static __inline u_int
inl(u_int port)
{
u_int data;
__asm __volatile("inl %w1, %0" : "=a" (data) : "Nd" (port));
return (data);
}
