| |
Hi,
My apologies if you've seen this already. I sent this out last week but have not seen any replies; perhaps no one has any suggestions, but perhaps it didn't go out properly for some reason.
---------- ................. ----------
Can anyone report success or failure with enabling DMA for the CS5530 IDE driver? I can get my system to crash or at least hang pretty reliably by using hdparm to turn on DMA while reading an MPEG-2 movie from my hard disk drive.
I don't think the movie playing is the relevent part; rather that it is heavily using the disk and driver.
The hard disk drive is the only rotating drive on the system.
Hardware: GCT Allwell set top box CPU: National Geode 266MHz GXM IDE controller: CS5530 Geode companion chip Linux: 2.4.3 Disk: IBM Deskstar, 46.1 GByte
Any comments or suggestions appreciated
Thanks, Michael
