From: "Timothy Thelin" When doing ioctl HDIO_DRIVE_TASKFILE, the ide_task_t's request pointer is never set, but flagged_taskfile and do_rw_taskfile pass it as a parameter to the prehandler. The kernel will oops taskfile pio-out commands because of this (taskfile pio-in doesn't use a prehandler). This fix sets the request pointer at the time the request is created to stop this oops.
