Description Sergey A. Sukiyazov 2007-10-23 23:58:02 UTC 
Most recent kernel where this bug did not occur:
Distribution: 2.6.10
Hardware Environment: SATA/SCSI CDROM (which uses sr_mod)
Software Environment: 

Problem Description:
When trying to get the drive status via ioctl CDROM_DRIVE_STATUS, with no disk 
it gives CDS_TRAY_OPEN even if the tray is closed.

ioctl works as expected with ide-cd driver. Here is the patch to get the same 
behaviour on SCSI drives for kernel 2.6.10. 2.4 branch have same problem.

Get from Debian bug #447337
(http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=447337)

Reproducible: Always

Steps to Reproduce:
1. Close empty CD tray.
2. call state = ioctl(device_handle, CDROM_DRIVE_STATUS);
3. state always gives CDS_TRAY_OPEN even if the tray is closed.

Resolve:
Patch for solve this problem present at Debian bug #447337 by URL:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=447337

I apply this patch. It work correctly. Now ioctl(device_handle,
CDROM_DRIVE_STATUS) returns right result.
