Just shutdown. No message at all.  Room at ~73 F w/ plenty of air to the unit. Previous entry in messages was 3 days earlier.

However, you bring up a good point.  I think I'll take compressed air to it and clean it.  It's been running 24x7 for a couple of years. No problems for the first year, but it's been flaky since I switched from 148 to 151 about a year ago.  However, I think that's the interrupt conflict w/ the nVidia server and the USB HID driver. Symptom is hung X server.

I've belatedly turned on Savecore, but don't expect that anything would have been saved. "famdm faulty -a" produces nothing.

Any suggestions on how to collect better data very welcome.  There are a great many thinly documented SMF options and I'm not sure where to even start looking through the source code.
