System Lock-up?

My system is Raspberry Pi 3 running owserver etc 3.1p5 with Sheepwalk
RPi3 adapter and RPi3a splitters giving me 8 channels. All devices are
powered, separately from the Pi. I use python code and pyownet to
monitor and control a mixture of about 35 DS1820 and DS2413

The system has been running fairly successfully for several years, but
today it failed. I think I can solve the basic failure, the thing that
puzzles me is that when I rebooted 2 of the 8 channels were missing. I
rebooted again, checked the cabled, still the same two channels
missing. I then shut it down and power cycled it and then all channels
were back again.

Is this a known issue? Is there any way to reset a channel other than
power cycle?

Thanks

Mick

Sometimes an IC gets into an inconsistent internal state when it gets
hit by e.g. a short power drop.
There's not much you can do about that.

Not that I know of.
Frankly, if the chip is in a state like the one you describe, I wouldn't
trust a partial reset anyway.

In reply to this post by Mick Sulley

Thanks for your comments Matthias. It happened again today, same
channels I think. Could it be temperature related? The Pi etc is in
the loft and it was around 40C in there today, so the Pi would be
somewhat above that.

Re: System Lock-up?

Have a look in /var/log/syslog and see if there are any interesting
messages around the time of failure. If syslog does not go back far
enough look in /var/log/syslog.1

There are loads of messages like this

That is before the problem, but then at the time of the problem it
changes to this

The action 17 may be nothing related, don't know. I have looked at
http://www.rsyslog.com/e/2007 and it didn't help me much.

Any ideas?

Thanks

Re: System Lock-up?

No USB related messages at the time of failure?

Re: System Lock-up?

In reply to this post by Mick Sulley

Thanks for your comments Jan, not what I wanted to hear but I'm sure you
are correct. The last time I used an oscilloscope I was in college and
had to wait for the valves to warm up before it would work :)

I do have a spare RPi3 adapter so I will try that first and see what the
log says then.
