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

My palmtop is a CS5530/MediaGX233 and seems stable with 2.4.*-ac. Im probably
not hitting the disk as hard as you though
