Even though READ_DMA_EXT error would suggest unreadable sector I observed this on a drive that's got a bunch of reallocated sectors (just slow to read), no pending or uncorrectable. This portion of the disk passes the most powerful ReadWriteReadCompare test in HDAT2 but if a read operation to such sector occurs under one of the newer kernels the drive immediately spins down, READ_DMA_EXT error is written to the SMART log and the drive is not avaliable in BIOS until next cold start.
