Hello,

We regularly compile and test Linux kernels every day during the merge 
window. Since Thuesday we have very high CPU loads because of the avahi 
daemon on our desktop Linux systems (Ubuntu, Debian etc).

Error message: avahi-daemon[2410]: ioctl(): Inappropriate ioctl for device

Do you know which ioctl, on which device ?
Can you take a trace of running avahi-daemon with 'strace' ?

Can you bisect ?
