Hi I've installed Fedora 25 on my Beaglebone Black for the reasons of
testing packages perhaps doing some quality assurance and helping with
test days. I used the KDE spin and I found that sddm-greeter
constantly consumes high amount of CPU, I can log in and it seem to
kick off KDE and it starts akonadi for a new user. I tried to strace
the process and I found that it calls gettimeofday
frequently, which is expected since it displays the time. I don't have
any explanation about why the CPU is so high. I tried to install
systemtap but I didn't find kernel-debug-core. Is there something else
I should do to debug this, is this a bug and should I report this? I
don't want to waste people's time with a bug that might not be valid
which is why I'm trying to investigate this as much as possible.
I know the beaglebone black doesn't have the greatest resources
available one CPU (1 GHZ) and 512MB RAM and on an sdcard (couldn't
find how to move it to the NAND).
