Hi,
I tried DMA on the mach64-0-0-4-branch now. All the gl application seem
to work fine. But after switching to another console and back (without
running a gl app at the same time:) the gl app's window is just black
after starting it, full CPU load in the kernel and the X-server reacts
very slowly. I get the following kind of messages in/var/log/kern.log
repeatedly (about one of these blocks per second):

I also wanted to try it without DMA. But just changing the #define
MACH64_DMA in mach64_drv.h didn't trigger any recompiling. Is there
something wrong with the dependencies?

Felix
