Hi,
i run NUT on a Raspberry Pi 3 Model B and after the latest OS Update i
get the following Error from KFENCE, the current OS Version is the first
with KFENCE so it possible that this Problem has was always existing.

==================================================================
The UPS is an Cyber Power Systems BR700ELCD with the following driver
configuration
driver = usbhid-ups
port = /dev/ttyUSB0
desc = "BR700ELCD"
pollinterval=10
pollfreq=15
Is that an Configuration ore Hardware issue?
That error I see above would prompt me to see if memtest86 would run on
that system. It sure looks like a stuck bit someplace in the memory.
Until proven otherwise, definitely a hardware problem in the memory.
Kind regards
Dirk
