Description of problem: Version-Release number of selected component (if applicable): 2.6.18-1.2239.fc5 How reproducible: always Steps to Reproduce: 1. boot with kernel 2.6.18-1.2200.fc5 or 2.6.18-1.2239.fc5 2. run "modprobe ide_cd" as root Actual results: FATAL: Error inserting ide_cd (/lib/modules/2.6.18-1.2239.fc5/kernel/drivers/ide/ide-cd.ko): Unknown symbol in module, or unknown parameter (see dmesg) Expected results: Loading the module and ability to access /dev/hdc Additional info: # dmesg | grep ^ide ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 ide-floppy driver 0.99.newide ide_cd: Unknown parameter `dma' ide_cd: Unknown parameter `dma'
looks like your /etc/modprobe.conf has a dma parameter in there. The module doesn't have that option, so it complains.
It hasn't, but I have a file in /etc/modprobe.d/ with such a line. options ide-cd dma=1 It was advised on http://freshrpms.net/docs/dvd/ for making ogle and mplayer play more smoothly, but this idea is obviously outdated now. I will tell them. The most amazing thing is that I didn't touch my /etc/modprobe.conf file in the last five monthes, and that the module stopped working only the last weeks. Probably some change happened in the kernel I didn't notice. I also thought about that, but since I was "grepping" for ide_cd instead of ide-cd, I didn't match the line... Anyway, thanks a lot, Dave.
