Hi,
I'm using a at91sam9260 processor on custom made board based on the
sam9260ek.
With the latest kernels (3.4-rc4 seem to be the last one working well)
whenever I try to connect the usb device port of the at91 processor to a
host I get the following error:

---[ end trace eb78f79a3e3c851b ]---
Kernel panic - not syncing: Fatal exception in interrupt
I've tracked the error to line 1099 of the file
drivers/usb/gadget/composite.c
This line is in the function "static int composite_setup(struct
usb_gadget *gadget, const struct usb_ctrlrequest *ctrl)"
line 1099: req->zero = 0; // req is NULL, this is where it blows up
The function is called from the function "static void
handle_setup(struct at91_udc *udc, struct at91_ep *ep, u32 csr)" in
drivers/usb/gadget/at91_udc.c on line 1246
line 1246: status = udc->driver->setup(&udc->gadget, &pkt.r);
So, from at91_udc_irq to composite_setup the path seems to be:
at91_udc_irq (line 1490) -> handle_ep0 (line 1289) -> handle_setup (line
1264) -> composite_setup
I've tried bisecting and it points to this commit:
f3d8bf34c2c925867322197096ed501ceab8085a
I don't really see what this patch has to do with the problem but I've
attempted bisecting several times and I always end up here.
Not sure if it helps but here is the bisect log
