Hi,

To the nut list, the last time nut changed was 2009-06-13:

2009-06-13 04:29:25 configure nut-cgi 2.4.1-3 2.4.1-3
2009-06-13 04:29:25 status unpacked nut-cgi 2.4.1-3
2009-06-13 04:29:25 status unpacked nut-cgi 2.4.1-3
2009-06-13 04:29:25 status unpacked nut-cgi 2.4.1-3
2009-06-13 04:29:25 status unpacked nut-cgi 2.4.1-3
2009-06-13 04:29:25 status unpacked nut-cgi 2.4.1-3
2009-06-13 04:29:25 status half-configured nut-cgi 2.4.1-3
2009-06-13 04:29:26 status installed nut-cgi 2.4.1-3

I made no changes to the nut configuration or install.

What did change was the motherboard.

From: Intel DG965WH -> Intel DP55KG

Then this problem began.

Justin.
