The same bug that this person reports here is happening to me: http://bugs.dragonflybsd.org/issues/1880
The system boots up until DBUS starts, then about 300 mSec later, I get this: ata1: FAILURE - oversized DMA transfer attempt... The same message occurs for several other devices, including acd0. I can boot to safe mode and remove this, but as X.org relies on dbus this makes a VMWare Fusion 5 + X11 + DragonFly BSD unusable. Since this bug was reported in 2010, I'm guessing nobody knows how to fix this or why this is broken? I suppose the minimal workaround is for me to manually configure my mouse and screen in X.org, but attempts to do this also lead nowhere (black screen). Warren
