Hello, I tried to activate watchdog on my beaglebone. It's working fine (restarts the board after 60 seconds of inactivity), problem is it fills dmesg log with lots of annoying messages:
$this->bbcode_second_pass_code('', '

There's always 9 of them every 5 seconds (I have 10 second tick interval in watchdog.conf), so the kernel log output is fairly useless and it fills system logs very quickly.
I found very little recent info about this other than it should have been fixed long time ago. Best fix a came across is the patch at the end of this thread http://e2e.ti.com/support/arm/sitara_arm/f/791/t/194467.aspx, though I haven't tried it yet. If I can confirm it works with current core/linux-am33x from archlinuxarm github repo (or come up with something that works), would it be possible to patch it there?
