I just installed FreeBSD-7 on an amd64 box. The new motherboard has
firewire builtin.
I wanted to disable dma via firewire, but as soon as I add
hw.firewire.phydma_enable=0
to /boot/loader.conf (which is what the man page suggests)
The box hangs on boot.
It detects the firewire controller, after that the sata disk and then
hangs.
Is this a known problem? Is there anything I can do to help debug this?
Lastly, if this is not easily fixable, would removing the firewire
driver from my kernel disable the DMA attack?
CU,
Sec
