Bug 429353

+++ This bug was initially created as a clone of Bug #428281 +++

Description of problem:

If I try to run it under the latest FC7 kernel I get the errors
  Selected: /dev/scd0
! :-( unable to MODE_SENSE(10) : Input/output error
! :-( unable to MODE_SENSE(10) : Input/output error
  
  ** Reading supported mode pages...
! :-( unable to MODE_SENSE(10) : Input/output error
! :-( unable to GET_CONFIGURATION LENGTH : Input/output error
! :-( unable to MODE_SENSE(10) : Input/output error

and the information on the media pages is all wrong like DVDs are shown as CDs

Under kernel 2.6.23.8-34 it works ok.


Version-Release number of selected component (if applicable):
qpxtool-0.6.1-5.fc7


How reproducible:
Just run under specified kernel
Drive is lite-on /dev/scd0: ATAPI    DVD A  DH20A3P   XP5Z

Actual results:
See description

Expected results:
Selected: /dev/scd0^M
Buffer capacity: 0x0800 (2048)KB^M
CD parameters page length: 0x3A^M
 2A 3A 3F 37 F1 77 29 23^M
 56 90 01 00 08 00 56 90^M
 00 10 56 90 56 90 00 01^M
 00 00 00 01 56 90 00 05^M

can you attach your dmesg output?

It's possible that the program is sending misformatted SCSI commands that are
being detected by the new length-checking logic in more recent kernels.

This problem occurs on kernel 2.6.24-rc7 too, and the sg3_utils mode sense
program (sg_modes) seems to work okay on all kernels I tried.

seems like reverting linux-2.6-libata-scsi-allow-short-commands.patch fixes the
problem.

Almost works.  The media page looks good and read transfer rate test works but
the DVD check PIE doesn't work. The GUI just says all test complete immediately.
In the terminal window it displays: 

set_scan_commands(LITE-ON )
** scan speed: 12x
Remaining: 13.000 sec...
:-( unable to LiteOn_init_pi_scan : Input/output error

** Starting LITE-ON  PIE/PIF sum8 scan...

Are there any error messages in the system log when this happens?

Nothing in dmesg or /var/log/messages
