MX/OpenMX network running
Today I got the mx/open-mx networking working for the front ends. This required some tweaking to the network interface configuration for the diskless front ends, and recompiling mx and open-mx for the newer kernel. Again, this will all be documented.

c1ioo timing glitches fixed
I also checked the BIOS on c1ioo and found that the serial port was enabled, which is known to cause timing glitches. I turned off the serial port (and some power management stuff), and rebooted, and all the c1ioo timing glitches seem to have gone away.
It's unclear why this is a problem that's just showing up now. Serial ports have always been a problem, so it seems unlikely this is just a problem with the newer kernel. Could the BIOS have somehow been reset during the power glitch?
In any event, all the front ends are now booting cleanly, with all dolphin and mx networking coming up automatically, and all models running stably:
