           Summary: kernel hangs when trying to read atip wiith cdrecord
    Kernel Version: 2.6.16.1
            Status: NEW
          Severity: normal
             Owner: bzolnier at gmail.com
         Submitter: lohmaier at gmx.de


Most recent kernel where this bug did not occur: 2.6.16.1 (yes, the same version
- it works with my dvd-burner, but not with my cd-burner), the 2.4 series worked
with both, but there I have been using ide-scsi)
Distribution: Mandriva 9.0 based
Hardware Environment:
cdrom: Cyberdrive CW058D - master on 2nd IDE
dvd: Pioneer 106D slave on prim. IDE
MB: elitegroup k7sem with sis chipset (SIS 5513)
Software Environment:
cdrtools 2.01.01a10

Problem Description:
When trying to use cdrecord with the cdburner, the kernel hangs (not completely,
only for cd-burning) and the system has to be rebooted. Even retrieving the
atip-information of a disc fails.
It fails only with the cd-recorder, not with the DVD-Burner. But when I tried
with the cdrecorder, burning with the dvd-burner won't work either until the
machine is rebooted.

Steps to reproduce:
I simply try to use "cdrecord dev=ATAPI:1,0,0 -atip" as root.
# cdrecord dev=ATAPI:1,0,0 -atip

----here it hangs and never returns---

If I run cdrecord with -V (i.e. scsi verbose), it reads:
[...]
Executing 'mode select g1' command on Bus 1 Target 0, Lun 0 timeout 40s
CDB:  55 10 00 00 00 00 00 00 3C 00
cmd finished after 0.002s timeout 40s

Executing 'get_configuration' command on Bus 1 Target 0, Lun 0 timeout 40s

CDB:  3C 00 00 00 00 00 00 00 04 00

Executing 'read buffer' command on Bus 1 Target 0, Lun 0 timeout 40s
CDB:  3C 00 00 00 00 00 00 FC 00 00

So the kernel doesn't timeout/return for some reason.

If that information is not enough to handle the process, please tell me what
else you need. Thank you.
