Hmm :-)

root@amd:/data/pavel# nmcli gen log level trace
Error: Unknown log level 'trace'
root@amd:/data/pavel# nmcli gen log level help
Error: Unknown log level 'help'
root@amd:/data/pavel# nmcli gen log level
Error: value for 'level' argument is required.
root@amd:/data/pavel# nmcli gen log level debug
root@amd:/data/pavel# cat /var/log/sys/log

Where do I get the logs? I don't see much in the syslog...

And.. It seems that it is "every other suspend". One resume results in
broken network, one in working one, one in broken one...

Thanks,
