Subject [PATCH] SCSI not showing tray status correctly
Date Mon, 27 Dec 2004 06:26:32 +0100
Digg This 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)
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.
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.
Submission of patch to lkml:
The patch has been sent upstream (again), we'll wait for their response.

Sorry for the delay here.
Please apply this patch instead, and confirm it solves the issue.
I went ahead and tested this myself. It needed some extra work (another patch backported first, and a fix applying after), but it's done now. Patches 2100, 2101, and 2102 queued for next gentoo-sources-2.6.24 release
Fixed in gentoo-sources-2.6.24-r1 (genpatches-2.6.24-2)
Not planning on backporting to 2.6.23 as this is more than a simple bugfix.
