I have hit this too with 4.11-STABLE I cvsup'ed last night. My system
is a Dual Athlon. If there is something I can do to help with this
I'll take a shot at it.
I say Julian had recommended some prints for debugging, and I added
those, but without a serial console it is tough for me to see if they
are getting printed early on. However the only print I can see is
right before the panic, "HEY WE GOT HERE!".
printf("HEY WE GOT HERE!\n");
KASSERT(cold || TAILQ_EMPTY(&usb_coldexplist),
("usb_cold_explore: busses to explore when !cold"));
while (!TAILQ_EMPTY(&usb_coldexplist)) {
sc = TAILQ_FIRST(&usb_coldexplist);
TAILQ_REMOVE(&usb_coldexplist, sc, sc_coldexplist);
printf("probing a USB 1.1 bus.\n");
With my old kernel (4.11-STABLE from end of Dec.)
