Bug Description
Binary package hint: k3b
When I start up K3B, it somehow disables DMA and then complains that the drive doesn't have DMA support enabled. I don't know how I could debug this problem.

Normally you have DMA enabled, isn't true?
According to https:/ /help.ubuntu. com/community/ DMA :
# See the what the settings are on /dev/hdc (where hdc is usually the CD-rom drive)
* sudo hdparm /dev/hdc
# If you get a line like using_dma = 1 (on), DMA is already enabled.
I'm looking at k3b sources and I see this:
#: k3bsystemproble mdialog. cpp:467
msgid "DMA disabled on device %1 - %2"
#: k3bsystemproble mdialog. cpp:471
msgid "Enable DMA temporarily as root with 'hdparm -d 1 %1'."
So you have to enable, as root, DMA by typing: sudo hdparm -d1 /dev/hdc
