Everything works great - I've already migrated all of the control software over to the new machine, but I am getting a *LOT* of silo errors in the syslog. Even 2400 baud (the SmartUPS) is resulting in these. Since this is a control system, I am getting hundreds of messages. I've managed to reduce this a bit by putting the thermostat, and a CM17A (bottlerocket), on the built-in COM port - but the UPS and CM11A are still generating a large number of messages. I did read in the puc manpage that if you get these, add in the option for fast interrupts. I did this, and am still getting the silo errors. It also mentioned that PCI interrupt sharing would be a problem - but nothing appears to be sharing that interrupt (irq 12) - at least in the dmesg. Now, this machine is no speed demon, but it should be fast enough to handle a PCI serial card. Integer speed is fairly quick, and it can even handle xdm with no problems. Just for giggles, here is the dmesg output for the system: Copyright (c) 1992-2003 The FreeBSD Project.
