Paul's linux-pmac-stable tree has changed quite a bit about ten days ago
when it was synced somewhat to Linus' and vger trees. It's been somewhat
unstable on my machine as well since then. I'm using the DMA support for
a month or so prior to that, and my machine was much more stable.
If you like, you can uncomment "#define SUPPORT_SERIAL_DMA" in macserial.c
to disable the DMA code and see if it changes anything.
