Hi, all. I've installed FC2 and configured ppp connection similar to my old FC1 configuration. It's works well, but when i try to shutdown ppp0 (ifdown ppp0), pppd starts using 100% of cpu and i get the following errors in /var/log/messages: kernel: unregister_netdevice: waiting for ppp0 to become free. Usage count = 1 I can't kill pppd as root with kill -9. Maybe it's a kernel-2.6 bug? (kernels 2.6.5-1.358, 2.6.6-1.427 and 2.6.7-rc3 from kernel.org) Any suggestions? Thanks.
