My workstation running 2.6.24-rc8 just hung during shutdown with an endless
(or rather I didn't wait more than a few minutes) loop of
unregister_netdev: waiting for ppp-device to become free. Usage count = 1
ppp-device was an active PPPoE device.
No more information currently.

i've seen such problems (locked up box with endless loop of usage count
== 1) with pppoe in the past, and it seemed to be related to dynamic
IPs. (i saw that well before 2.6.24 - reported it once to davem)
It seems to have stopped when i stopped using ipsec and started using
vpnc. (but no firm info - this was sporadic - happened every few months
or so) Are you using ipsec and dynamic IPs by any chance?

Same as http://lkml.org/lkml/2008/1/20/27? See also follow-up to that.

Now that you mention it, this happened to me too this morning. My
system stops the ppp interface (pppoe) and starts it again (my provider
shuts down the link every 24 hours, I want that to happen during the
night, so I do a ifdown ppp0).

Kernel ipsec was active yes. However I normally don't see it although
it is often active, that was the first time I think
(except long ago)

and the ISP uses dynamic IPs.

Actually, I'm getting something similar:
usb 2-2: USB disconnect, address 23
PM: Removing info for No Bus:usbdev2.23_ep83
usb0: unregister 'cdc_ether' usb-0000:00:1d.0-2, CDC Ethernet Device
PM: Removing info for No Bus:usb0
unregister_netdevice: waiting for usb0 to become free. Usage count = 1
unregister_netdevice: waiting for usb0 to become free. Usage count = 1
unregister_netdevice: waiting for usb0 to become free. Usage count = 1
unregister_netdevice: waiting for usb0 to become free. Usage count = 1
unregister_netdevice: waiting for usb0 to become free. Usage count = 1
unregister_netdevice: waiting for usb0 to become free. Usage count = 1
PM: Removing info for usb:2-2:1.0
PM: Removing info for No Bus:usbdev2.23_ep81
PM: Removing info for No Bus:usbdev2.23_ep02
The unregister_netdevice made it onto console, that means pretty
severe log level. Happened while playing with openmoko connected with
USB cable.

No, this is a different bug Andi is seeing and it was
recently introduced:

This isn't PPPoE specific. It has also been seen with e1000, madwifi
and an intel based card. It was introduced by a Jan 10 commit post rc7
(sorry, don't have the details right now - my laptop died yesterday).
A bugzilla has already been opened.
