Subject: [ 08/19] libata: Set max sector to 65535 for Slimtype DVD A DS8A8SH drive
Date: Wed, 10 Apr 2013 15:50:31 -0700 [thread overview]
Message-ID: <20130410225027.669408132@linuxfoundation.org> (raw)
In-Reply-To: <20130410225026.833809117@linuxfoundation.org>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Shan Hai <shan.hai@windriver.com>
commit a32450e127fc6e5ca6d958ceb3cfea4d30a00846 upstream.
The Slimtype DVD A DS8A8SH drive locks up when max sector is smaller than
65535, and the blow backtrace is observed on locking up:
INFO: task flush-8:32:1130 blocked for more than 120 seconds.

The above trace was triggered by
"dd if=/dev/zero of=/dev/sr0 bs=2048 count=32768"
It was previously working by accident, since another bug introduced
by 4dce8ba94c7 (libata: Use 'bool' return value for ata_id_XXX) caused
all drives to use maxsect=65535.
