Subject: BUG on fs/inode.c:1442 (linux 3.3.1 and 3.3.2)
Date: Sun, 15 Apr 2012 23:56:01 +0200 [thread overview]
Message-ID: <20120415215601.GV1927@vicerveza.homeunix.net> (raw)
[-- Attachment #1: Type: text/plain, Size: 427 bytes --]
Hello,
destroying my openvpn client connection (SIGINT to openvp), in linux 3.3.1 and
now also in 3.3.2, I noticed this BUG in dmesg (attached).
It's a vanilla 3.3.2, at this shot.
I know it never happened to me in any 3.2, but I did not try 3.3.0.
I attach the .config. And I have the debug info for this kernel too, if this
helps someone find a fix. But I imagine it's easy to reproduce.
Thank you,
Lluís.
