Hi,
DMA is enabled as far as I can see.
hdparm report "Capabilities" as :
DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 udma5*udma6
Cycle time: min=120ns recommended=120ns
dmesg shows :
ata2: PATA max UDMA/100 cmd 0x170 ctl 0x376 bmdma 0xBFA8 irq 15
ata2: dev 0 ATAPI, max UDMA/33
ata2: dev 0 configured for UDMA/33
I think problem may be more to do with the yv12 overlays. But I
find it surprising that this should not be supported by the
fglrx-driver or the VESA driver. I am not sure how I can
confirm this or find a workaround.
regards
b thomas
