Subject: [BUG]: 2.4.10 lockup using ppp on SMP
Date: Fri, 28 Sep 2001 17:03:06 +0200 [thread overview]
Message-ID: <3BB4912A.414B809A@internetwork-ag.de> (raw)
Hi,
2.4.10 (and all its 2.4.x predecessors) lock up in ppp_destroy_interface. Thanks
to the kdb I got the two tracebacks below - the all_ppp_lock interferes with
some other (socket?!) lock...
Any help is VERY much appreciated!
Thanks
Immanuel
