Description Marat N.Afanasyev 2009-05-10 01:00:07 UTC 
	any time I try to copy a large file from dvd, I encounter a problem with 
	'acd0: setting up DMA failed', setting acd0 to pio mode partially solves 
	problem

Fix: 

workaround: atacontrol mode acd0 pio4
	solution: revert ata(4) to 2008-11-25 revision
How-To-Repeat: 	place a disk into drive and try to read a partially big file

State Changed
From-To: open->feedback

To submitter: can you please reboot, selecting "boot with verbose 
logging" from the menu, and show the bits of your dmesg relating 
to the ATA controllers and devices?  Also, can you then try the 
DVD drive again, and show any extra messages printed?

This is a multi-part message in MIME format.
Comment 4 Marat N.Afanasyev 2009-05-14 23:28:41 UTC 
and if I set UDMA66 mode for acd0 again I have the following messages:

May 15 01:46:19 zealot kernel: ENOMEM 0xffffff00a2266000 on 
0xffffff0005444800(acd0)
May 15 01:46:19 zealot kernel: acd0: setting up DMA failed

So, as soon as I have 'Setting DMA failed' I have to switch to PIO mode 
until reboot
