Hopefully someone can help me here. My problem is with my Samsung DVD drive. Right now I am running SuSE 8.1, but I had the same problem when I had SuSE 8.0 and I never tried to fix it. Basically when I watch a movie, or just read data from the drive after a while the drive locks up. When I watch a movie it seems to happen about half way through the movie, but when I just transfer data off of the drive it only takes about 20 minutes to freeze. This makes me think that it is related to the amount of data read, not the amount of time. Anyway when I logout I see the following messages:

linux kernel: scsi: aborting command due to timeout : pid 6931 , scsi0, channel 0, id 1 , lun 0 0x28 00 00 10 17 a8 00 00 3f 00
linux kernel: SCSI host 0 abort (pid 6931) timed out - resetting
linux kernel: SCSI bus is being reset for host 0 channel 0
linux kernel: hdd lost interrupt

hdd is of course my DVD drive.

The only way I can fix it is to turn off my computer and wait for a while. If I don't wait that long, the DVD drive will lock up sooner when I try to read from it again. To me this seems like a hardware problem, but in windows the drive works fine. I can't read from it as long as I want.

Please give me some ideas on how to fix this, because I'm getting tired of watching the first half of movies when I'm in linux!

Thanks,

is DMA mode for hdd enabled ?
if yes: try disabling DMA

Well, DMA was already off so that wasn't the problem. Any other ideas?
