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?
Responsible Changed From-To: freebsd-bugs->gavin Track

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 -- SY, Marat
For bugs matching the following criteria: Status: In Progress Changed: (is less than) 2014-06-01 Reset to default assignee and clear in-progress tags. Mail being skipped
Obsolete after import of new ata stack.
