another datapoint on ide dma issue with via

[John F Davis]

Hello

Another thing I have noticed is that if I copy the files to and from disk 
prior to starting xine playback it will work.

ie. This works:


hdparm -d1 /dev/hda
mount /dev/hda2 /mnt/disk

Run in four windows simulataneously:

while true; do
        /root/driver Super.mpg $1     " This program uses mmap io to copy 
the src file to the dest file."
        sync
        md5sum Super.mpg
        sync;
        md5sum $1;
        rm $1;
        sync;
done

Kill all the scripts.

startx
start xine
run the super.mpg video from /mnt/disk.  It works flawlessly.



and This doesn't:

reboot
hdparm -d1 /dev/hda
mount /dev/hda2 /mnt/disk
startx
start xine
run the super.mpg video from /mnt/disk.  I will 
get nfsroot errors about nfs server not responding.
then ksymoops with xine making the last system call.
