i cannot read or write any disk inserted in my
acd0 <PIONEER DVD-RW DVR-111D/1.29>
when this device in udma mode. kernel endlessly repeat that
acd0: setting up DMA failed
and I can access my data on dvd or cd only if I set
atacontrol mode acd0 pio4
Does anybody have such a problem too? is there any ways to bring this
device into udma mode again?
dmesg:
