I think these pritout messages are not only for debugging purpose but
a kind of error notification, for adapter resetting is error.
I prefer that these messages are always output wheter debugging mode is enabled
or not, but if it is not hoped to be always output to syslog, another place
(like a private ring buffer) is also acceptable.
Now I'm considering to output to private pring buffer.
