Hello, I hope this is the correct place to put a bug report in. I do
not subscribe to this mailing list, but feel free to send PM in case
you need additional info. You shoudn't :-)

After installing Ubuntu 13.10, I noticed kern.log growing faster
than you could look at. Within a few working hours, kern.log was

quoted

6GB!

The reason is that I intentionally disabled WiFi on this laptop by
turning the HW switch off. However, this makes iwl3945 write a log
entry into kern.log every few microseconds!

The workaround is to turn the HW switch on. The bug fix would be to
write just a single line to kern.log.

This message is printed when someone try to UP device when RF kill
switch is on. Either you did not compile kernel with CONFIG_RFKILL or
your user space network management software does not handle rfkill .

Though maybe it shouldn't actually print a dmesg error when that
happens?  Lots of software (scripts included) might try to open the
device but not really know much about rfkill...  Is there a way to print
it once-per-rfkill instead maybe?
