Promise RAID drivers for SuSE 8.0
Take it up with Promise if you are using their binary raid modules

I have exactly the same problem with the same motherboard, but:

- I have only one processor (Athlon 1900 XP)
- I don't have a Promise controller, I use the motherboard IDE controller

With Redhat 7.3 stock kernel if I try:

dd if=/dev/hda5 of=/dev/null bs=1048576

the system hang. If I configure the disk to don't use DMA the system runs fine.

Hi Bruno,

I tried using dd to copy 100MB from /dev/sda3 to /dev/null using my Promise FastTrak TX2000 and my system hung when I was using DMA and also hung when I booted SuSE 8.0 (2.4.18) adding "nodma" to the kernel parameters (Is this the correct way to disable DMA in linux?).

Tonight I'm going to try doing heavy I/O without my promise controller to see if there is a problem with the MSI K7D master and linux DMA copying.

Regards,

Chris

I'm not sure in SuSE, in fact the last time I take a look at the code, the nodma parameter is not used in the standard kernel.

For disabling DMA I use:

hdparm -d 0 /dev/hda
