Hello.
I can reliably reproduce an Oops on our Freescale 8347:e
with a Logitech webcam. Strange part is that I can only do
it using usb-audio, never with the same device using uvcvideo
or usb-storage.
It usually occurs within seconds of streaming from the
USB-audio device. I have ported everything on our platfrom from
our 2.6.32 kernel to 3.3.2. USB never gave me an issue on 2.6.32
and I can't figure out why it would die in ehci_work like this.
Unable to handle kernel paging request for data at address 0xbe903df8
