Hi Ed,

Thanks for the hint re/ how sending SMS from shell; I will add this to
my howto; works nicely.

I'm attaching the screenshoot which I took right after re-boot and have
here the syslog: http://www.unixarea.de/syslog.ublina

The reboot was at 19:49:02, the last line before in syslog was 19:26:17;
I have glanced a bit through the log but can not see any unusual.

I will try to catch the enemy with a loop like the above logging every 5
minutes or so the:
- battery state
- temp state
- a complete 'top -b -n1' output

I will report back

	matthias
