It looks like some device is not handling a low power mode. Notice that the log ends for quite some time prior to the “usb_suspend_both” error. You could try disabling USB autosuspend for a bit to see if the error goes away. Try either/both of these:
-
Edit /boot/extlinux/extlinux.conf, find the “APPEND” line, and at the end add (space delimited) " usbcore.autosuspend=-1"
-
Edit (or create) “/etc/modprobe.d/usbcore.conf”, and add this line (if the file does not already exist and you create one, then later you can just delete the file): “options usbcore autosuspend=-1”.
If you wait for some time to pass when the system might have otherwise put some USB devices into low power mode, then the error might no longer exist. If this is the case, then you’ve narrowed it down to low power mode issues (and this is likely a problem with a USB device).
