My workstation running 2.6.24-rc8 just hung during shutdown with an

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?
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.
