I rebooted cymac0 a couple of times. When I first got here it was just frozen. I rebooted it and then ran a model (x1ios). The machine froze the second time I ran ./killx1ios. I've rebooted it again.
For context, there's a is stand-alone cymac test system running at the 40m. It's not hooked up to anything, except for just being on the martian network (it's not currently mounting any 40m CDS filesystems, for instance). The machine is temporarily between the 1Y4 and 1Y5 racks.
