Kernel error, after shutdowning ppp device

["?=sanya G=?koi8-r?Q?"]

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.

If got the same messages in regarding to ppp, it looks like ppp is not
stable......
does anybody had the same trouble ??

(PS i did a clean install of Fedora Core 2, after this a linuxiant 8k stacks
kernel)
Jun 14 20:15:06 borderline kernel: unregister_netdevice: waiting for ppp0 to
become free. Usage count = 1
Jun 14 20:15:16 borderline kernel: unregister_netdevice: waiting for ppp0 to
become free. Usage count = 1

Jun 14 20:14:16 borderline mxstream: Shutting down mxstream connection:

Jun 14 20:14:21 borderline last message repeated 4 times

With kind regards

I had the same problem with kernel 2.6.6.-1.424.
The problem is gone in 427 for me. Haven't tested kernel 435 yet, cause I'm
the only user on this machine...

I'm not sure if it's a pppd bug - possibly a odd combination of a kernel and
pppd bug ?

Cheers,
Hannes.
