title Red Hat Linux (2.4.18-26.8.0)
   root (hd0,0)
   kernel /vmlinuz-2.4.18-26.8.0 ro root=LABEL=/ ide1=0x170,0x376,15
   initrd /initrd-2.4.18-26.8.0.img
title Red Hat Linux (2.4.18-14)
   root (hd0,0)

PBHarris, thanks for all of your help, I am greatful.

I added that to my grub.conf, rebooted, and played an ogg from a mounted cdrom. It worked for about 3 minutes and then locked up again.

I guess I'll just have to move those files then to my /hda6 and play them there in order to prevent this.

thanks

hummsss....
well lets try this - if you wanna - edit the file /etc/sysconfig/hardisks and remove the # in front of the item that says dma=1 (or something similar...) i am not at my linux puter at this instant so i am going by memory.

Hey!!!

I uncommented the following from /etc/harddisk/

Code:

USA_DMA = 1

So far it is working pretty well...

thanks for the help

Celebrated too early...

I been playing oggs from a mounted cdrom, and started having the same problems again...

Someone from my lug, http://www.olug said to do the following:

Put these lines at the end of you /etc/rc.d/rc.local file:

hdparm -c 1 /dev/hda
hdparm -d 1 /dev/hda

The first one turns on 32bit io, the second turns on dma.

Verify with:
hdparm /dev/hda

Repeat for each hard drive.

I did this and tried it but still keep getting this

Code:

 

dmesg | grep hdc: lost interrupt

I then commented out what I put in for /etc/sysconfig/harddisk and so far it was worked ok...

If you are using a (I think this is the lower limit, may be 33) UDMA 66 compatible drive on a UDMA 66 or better IDE controller, you will want to use an 80 pin ide cable. I used to get that all the time on three of my systems that had similar circumstances as what I described, and all were using older 40 pin cables. After replacing them all, everything shutup.

HTH.
