Subject: [PATCH] cdrom: longer timeout for "Read Track Info" command
Date: Mon, 1 Jan 2007 18:36:24 -0800 [thread overview]
Message-ID: <20070102023623.GA3108@sgi.com> (raw)
I have a DVD combo drive and a CD in which the
"READ TRACK INFORMATION" command (implemented in the
cdrom_get_track_info() function) takes about 7 seconds to run.
The current implementation of cdrom_get_track_info() uses the
default timeout of 5 seconds. So here's a patch that increases
the timeout from 5 to 15 seconds.
The drive in question is a TSSTcorpCD/DVDW SN-S082D, and I have
a Silicon Image 680A adapter, in case that's of interest.
