Red Hat Bugzilla – Bug 91069
(IDE DMA)Can't mount CD: "tray open" messages
Last modified: 2007-04-18 12:53:48 EDT
Description of problem:
Can't mount CD on my (old) computer
(Mounting CD's in Red Hat Linux 9 installer (both auto and
in Ctrl-Alt-F2 console) worked fine.)
I then reinstalled RHL9 and after installation
got the same situation...
My previously installed Linux was Red Hat Linux 8,
(kernel 2.4.18-4), and in this version of Linux all my CD's mounted ok.
Older versions of Linux (debian 2.2, 3.0) and Windows worked fine too...
System BIOS: Award Modular BIOS v4.51PG
BIOS ID: 07/21/97-i430TX-2A59ISM9C-00
System Chipset: Intel Corporation 82439TX 430TX System Controller
System Mainboard Model: ACORP-5TX32 Ver.C 08/07/1997
CD-ROM: CREATIVE CD2422E MC102 (CD 20X Rd)
Version-Release number of selected component (if applicable):
always on my computer (see hardware list above)
Steps to Reproduce:
1. mount /dev/cdrom
ide-floppy driver 0.99.newide
hdc: ATAPI 20X CD-ROM drive, 0kB Cache, DMA
hdc: tray open
end_request: I/O error, dev 16:00 (hdc), sector 64
repeats last two messages 20 times, then prints
mount: not a directory
and does not mount CD.
Created attachment 91755 [details]
filled "reporting-bugs" form from kernel source
Included in this attachment are logs of console, /var/log/messages,
/var/log/dmesg, processor and harware information, etc.
Ater disabling DMA (by running hdparm -d0 /dev/hdc) everything works fine.
Looks like this CD needs adding to the nodma blacklist. Thanks
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
