Comment 8 for bug 805423

landscape-common installs a script in /etc/update-motd.d to display a banner with some basic system information.

It will not run the main landscape-sysinfo binary if the load is higher than the number of cores, see /usr/share/landscape/landscape-sysinfo.wrapper:

#!/bin/sh
cores=$(grep -c ^processor /proc/cpuinfo 2>/dev/null)
[ "$cores" -eq "0" ] && cores=1
threshold="${cores:-1}.0"
if [ $(echo "`cut -f1 -d ' ' /proc/loadavg` < $threshold" | bc) -eq 1 ]; then
    echo
    echo -n " System information as of "
    /bin/date
    echo
    /usr/bin/landscape-sysinfo
else
    echo
    echo " System information disabled due to load higher than $threshold"
fi

Do you think it was landscape-sysinfo running that made your login take more than 60s and thus timeout?
