Hello all:

I have suse 10.1.
The system has a cd-rw and a dvd-rw drive.
After booting the system Yast dma status check reports that 
for both drive the dma is on.  After a certain time checking 
again Yast reports that dma is off for both drives.
If I want to turn dma in Yast it gives an error message:

"An error occured while activating the changes. Cannot set 
required mode '%1' for device %2."


At the same time according to hdparm dma is on:

# hdparm -i /dev/hdc

/dev/hdc:

 Model=PIONEER DVD-RW DVR-108, FwRev=1.20, SerialNo=
 Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs 
nonMagnetic }
 RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0

 (maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0

 * signifies the current active mode

# hdparm -i /dev/hdd

/dev/hdd:

 }

 IORDY=on/off, tPIO={min:383,w/IORDY:120},

 PIO modes:  pio0 pio1 pio2 pio3 pio4
 DMA modes:  sdma0 sdma1 sdma2 mdma0 mdma1 mdma2
 UDMA modes: udma0 udma1 *udma2

 * signifies the current active mode

NeroLINUX also claimed that dma was off, and burning a 
regular dvd took 40 min when the speed was set to 6x so I 
concluded that dma was off. (Is that correct?)

Questions:
1. What can cause that dma is turned off?
2. How can I check dma staus on the command line w/o 
starting yast?
3. How could I turn dma on?

TIA,
IG
