APC Smart-UPS X 1500 Restart Issue.
Hi All, I have installed nut-2.4.3. I have manually modified the files apc-hid.c and udev-rules to support 5G APC UPS. I took sample code from the 2.5 development tree. Shutdown process is working very well -- upsmon creates the file /etc/killpower - shutdown script checks for the file and issues /sbin/upsdrvctl shutdown - UPS cuts the power off. All is well. I am facing an issue when power is reapplied to the UPS. Following is the behavior I see: 1. Power comes back to the outlet. 2. System powers up. 3. When system reaches "Starting udev", UPS power cycles again. Above cycle repeats forever. If I cut the power to UPS for ~20 mins and then re-apply power to UPS, system comes back fine. I was searching through the mail-list and I see some other people are experiencing similar issue: Link: http://lists.alioth.debian.org/pipermail/nut-upsuser/2010-July/006118.ht ml I was wondering if there is a resolution for this issue.
