Hey guys,

For as long as I can remember since rt2500pci was my wireless driver, rfkill inserts data once per second into my keyboard stream. Normally, X ignores these data and the problem simply manifests itself as keyboard repetition being stopped once per second.

I think there may have been some change between 2.6.24 and 2.6.25-rc5 which prevents me logging in on a console. Now, during boot, my console is spammed with ^@ (i.e. \0) once per second and I can't log in on the console (because my password is interspersed with ^@!). X still works.

If I remove the rt2500pci and dependant modules, the output stops. If I echo 0 > /sys/class/rfkill/rfkill0/state, the output stops. Otherwise, 0x60 (96) bytes of this output appear every second:

I hope there is enough structure and repetition in this output to allow you to find the source. I didn't bother to bisect to find the cause of the ^@'s on my console, since I don't think it's the underlying problem.

Thanks,
Bruce
