From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20040922 Galeon/1.3.18 Description of problem: I have noticed for some time (at least since the RH9 kernels, when I got this laptop) that I cannot use my external DVD to play DVDs without recompiling the kernel. It will read and write CDs just fine. After some searching on Google and messages passed back and forth with several people, I found that the DVD drive was not reporting itself correctly. The problem is "fixed" by modifying the file drivers/cdrom/cdrom.c as follows (this is typed in; for some reason point&click editing is not working here): ===== #diff drivers/cdrom/cdrom.c drivers/cdrom/cdrom.c~ 2752,2753c2752,2753 < // if (!CDROM_CAN(CDC_DVD)) < // return -ENOSYS; --- > if (!CDROM_CAN(CDC_DVD)) > return -ENOSYS; 2773,2774c2773,2774 < // if (!CDROM_CAN(CDC_DVD)) < // return -ENOSYS; --- > if (!CDROM_CAN(CDC_DVD)) > return -ENOSYS; ===== Is there perhaps a better way to ask the external DVD drive whether it is in fact a DVD drive, so that I don't have to build a new custom kernel every time I update the kernel? John Version-Release number of selected component (if applicable): kernel-2.6.9-1.6_FC2 How reproducible: Always Steps to Reproduce: 1. Install new kernel. 2. Try to play DVD, with ogle, xine, mplayer, or any other player. 3. Rebuild kernel with above change. 4. Try to play DVD with new kernel. Actual Results: DVD would not play with stock kernel. DVD would play with rebuilt kernel. Expected Results: DVD should play with stock kernel. Additional info:
Please provide the vendor/model information from /proc [the exact strings]. I can then try and find out what is going on and also whether a check recognizing that drive is needed.
Assuming you're after the strings from /proc/cpuinfo (I should warn you that we are really pushing the envelope of my knowledge here; I'll do what I can, but bear with me a bit, please), they are: vendor_id: GenuineIntel model name: Intel(R) Pentium(R) M processor 1700MHz Is that what you're after?
Not quite but not to worry. If you can attach the results of running "dmesg" after boot that will include the pieces I do need.

I recently upgraded my distribution to Fedora Core 3, and the problem has gone away. I can now play a DVD with no problem, without having to rebuild the kernel. I am inclined to call this fixed.
