https://bugzilla.kernel.org/show_bug.cgi?id=215740 --- Comment #13 from Alan Stern (stern@xxxxxxxxxxxxxxxxxxx) --- Those two stack traces are essentially the same as the first one reported. They all contain the following key sequence of function calls: dma_map_page_attrs usb_hcd_map_urb_for_dma usb_hcd_submit_urb usb_start_wait_urb usb_control_msg hub_ext_port_status hub_event process_one_work It doesn't look like they add anything new. -- You may reply to this email to add a comment.
