syslog, kern.log, messages are filled

[blueforesticarus]

running copter 3.7 dev:

Ardupilot seems to be filling up the disk with log messages in /var/log/kern.log /var/log/syslog and /var/log/messages.

Most of the messages are like the following.

[  481.993933] rcio spi1.0: rcio_pwm: requested update on 1 to 50
[  481.994056] rcio spi1.0: rcio_pwm: requested update on 2 to 50
[  481.996450] rcio spi1.0: rcio_pwm: requested update on 0 to 490
[  481.996592] rcio spi1.0: rcio_pwm: requested update on 0 to 490

About hundred of theses are logged every second and over the course of a couple hours it fills a 32 gigabyte sd card.

Which flight controller? I guess one of the linux boards?

[blueforesticarus]

It is a raspberry pi 3 with navio2.

Opening up mavproxy I notice that I get a message:

Critical: AP_Logger: stuck thread

On the other hand the messages in syslog say they are originating in the kernel:

Apr 18 01:12:28 Drone kernel: [ 2735.448024] rcio spi1.0: rcio_pwm: updated freq on grp 0 to 490

So this may be in the navio2 drivers, rather than ardupilot code.

My syslog also gets quite big with non human readable stuff... (Using ardurover) Is AP_Logger: stuck thread () the problem?
