I'm seeing this in the initrd (with the dev_ksmg_record line added to clarify
where the error is coming from):

[ 6.570846] systemd-journald[251]: Too many messages being logged to kmsg, ignoring
The error message was misleading, since it sounds like there's an issue with
symlinks, but the device simply doesn't exist. But I think we should suppress
the message altogether. journald spewing messages like this fills up the logs
for no benefit. The sd_device_new* functions can legitimately be used for
"invalid" devices, e.g. to check if they even exist. We have no idea for what
purpose the caller is creating the device object, so let's not log this at all.
The caller can log if appropriate.
