Hi,
I have a TOSHIBA Model: DVD-ROM SD-M1201 on a NCR53C810 SCSI
controller.
Trying to do a DVD_AUTH ioctl I get a SCSI command timeout and after
that a bus reset (see below) beginning with kernel 2.3.99-pre1 through
-pre5 . It works without a problem in kernel 2.2.14 and 2.3.51.
The code is called in the css code which is for example part of oms in
the livid project. You can test it simply using the tstdvd utility
which tries to read the disk-key and has to authenticate to the DVD
first.
A minor problem is, that this ioctl returns with error but errno is
only set to 0.
I suppose that the problem is in the just then updated ncr53c8xx
driver (version 3.2g) because people with an adaptec reported no
problems here.
System is an asus P2D board with two PIII 450.
Any ideas here?
Christoph
