Mark- The system is Tyan s2723, which includes an integrated graphics controller, and I've connected a monitor to this port. I don't start the X-windows software however, and I don't use this monitor. For starting my scripts, I connect using SSH via an Ethernet port, however everything operates in background mode, there is no output to any console while these tests are running - just log files.
I do receive an occasional Double/missed interrupt message - but very few of these. Will report the results of testing your new driver code! Thanks Scott Scott M.
