With the recent addition of several kernel module dependencies needed by tr181-qos manager we've started experiencing issues with command prompt detection in labgrid's shelldriver component. It's likely related to longer kernel module loading times, which is then having impact on delayed and longer kernel messages output on serial console, thus interleaving labgrid command markers with kernel messages and causing command prompt detection unreliable. Current serial console loglevel is set to debug log level (KERN_DEBUG=7) which makes kernel output very verbose and in some corner cases it's causing interleaving of messages on serial console which makes currently controlling of the DUT via labgrid framework very unreliable. Fixing this properly via PCF-617 upstream in the labgrid framework is going to take some time, so as a temporary workaround we're going to decrease default kernel log level to warning (KERN_WARNING=4) which limits kernel log output to the serial console a lot. Those kernel log messages are not lost, they're still available in syslog's messages log file.
