[Nut-upsuser] APC Smart-UPS X 1500 Restart Issue.

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:

I was wondering if there is a resolution for this issue.
