Subject: [PATCH 3/3] libata-dev: wait idle after reading the last data block
Date: Sat, 25 Mar 2006 18:18:15 +0800 [thread overview]
Message-ID: <442518E7.8020607@tw.ibm.com> (raw)
In-Reply-To: <44242C25.3020002@pobox.com>
Some CD-ROM drives are slow to clear DRQ, after the last data block
is read by PIO. Use ata_wait_idle() after reading the last data block.
