Strange R64 behavior with a USB keyboard on 0.6.44

[gene83]

Did you manage to resolve the spurious output from the keyboard presses.

Hi,

No, there has been no resolution.  I assume that it will need the next update to fix,

I can also reproduce this on the 0.6.44 bionic images with a wireless keyboard. I'd say this will go away once the dmc memory issues are resolved.

The referenced commit does indeed look to be the cause of the messages. From the looks of things you shouldn't be seeing those messages by default, as the default kernel log level for the images appears to be '4' (do a cat /proc/config.gz | gunzip | grep LOGLEVEL_DEFAULT to see what your kernel was compiled with) and this is a level 6 message (meaning a log level greater than 6 is needed to see it). Anyway, If you check /proc/sys/kernel/printk, and and the number is 7 or higher, do a echo 4 > /proc/sys/kernel/printk when logged in with su or some such method of getting around the fact you can't sudo when piping. That should stop you seeing the rockchip-sip messages. However, it won't stick, so will need to be reapplied after a reboot or power cycle, so you may want to set it in rc.local, etc.

I can confirm that this solved the problem.  Thank you!  As an FYI, LOGLEVEL_DEFAULT was 4. Printk was  7 4 1 7.  Echoing 4 to it turned it into 4 4 1 7, and this solved the error message issue.

Thank you!

This also fixed it for me. Thank you
