Hi,
Applied this to 2.6.21-5 along with an older version of dyntick and cfs v18, durring boot I got:
[ 54.154077] hci_usb_isoc_rx_submit: hci0 isoc rx submit failed urb ffff81004ec55628 err -38
[ 54.154086] hci_usb_isoc_rx_submit: hci0 isoc rx submit failed urb ffff81004ec55628 err -38

Has this patch uncovered a problem in bluetooth or is it a problem with the patch?
