When we press ctrl-alt-del,kernel_restart_prepare will invoke cfi_intelext_reboot which will set flash to read array mode, but later when device_shutdown is invoked which may put current work queue to sleep and other process may be scheduled to running and programming flash in not FL_READY mode again. So we can't boot up if this flash is used for bootloader. Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: David Woodhouse <[email protected]>
