I am having a weird problem with Suse 10.1. I find that my system locks up at the start screen so I pressed ESC and found the following:

ide-cd: 0x3
hdd: lost-interrupt

The last thing I did was enable DMA on my DVD burner but it was still sometimes hanging even before I changed to DMA. My DVD burner does have DMA since I was using it with DMA enabled (UDMA/33) with Suse 10.0.

Is this a hard drive issue maybe? I did run a hitachi drive checker (eventhough my drive is WD it works fine) and it didn't find anything.

My system specs are the following:

AMD X2 3800+ (dual core enabled)
ASROCK 939 motherboard
ATI 9800 Pro
2GB ram
Western Digital ATA 7200rpm IDE drive
BenQ DVD burner (master secondary)hdc)
AOPEN CD burner (slave secondary) hdd

If I recall, both devices that are on the same cable need to support DMA. Are you sure the BenQ dvd burner supports DMA?

Yes it does it had DMA enabled in Suse 10.0 and I enabled it now and it shows up in DMA part in the YaST panel as UDMA 33. The drive is new so it does support DMA.

I am just wondering if its not a hard drive issue or not.

I presume that you have it this way.
1. Hard drive is on primary cable all by its' self.
2. Dvd and cd burnner on the same cable.

If it is this way, the hd should be isolated and check to see if you get the same error. I would check and see if your hd does support and it is enabled by the jumpers on the hd. Be sure you are using the corect cables. ATA drives use different cables that EIDE. Also, I would go back and check the maker of your motherboard and check to see if DMA is supported. I am not familiar with that mb, so that is why I am asking about the DMA support. Also, if you goto western digital online, you can download diagnostic software and run a check. Sorry, but I don't have anything else to say. Also, I would check and see if you need something special for the kernel for the hd. Remember, it is a .1 version. I would stay with even numbers. They tend to be the more stable versions.
