X-BeenThere: freebsd-stable@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 31 Dec 2008 14:27:00 -0000 Hi, One[1] of my machines have recently had a couple of panics wile running FreeBSD 6.4-stable / amd64: root@kg-quiet# uname -a FreeBSD kg-quiet.kg4.no 6.4-STABLE FreeBSD 6.4-STABLE #25: Fri Dec 5 23:26:19 CET 2008 root@kg-quiet.kg4.no:/usr/obj/usr/src/sys/QUIET amd64 The machine works as a cheap fileserver (running Samba) and has a number of external disks attached (one firewire, several usb). A work log for FreeBSD on this machine is here[2]. So I used kgdb to make a couple of backtraces of the dumps, in case it is useful. The first panic mentions smbd, dump info and backtrace kan be found here[3]. The next panic mentions ohci0 and ohci+ as the process, , dump info and backtrace kan be found here[4]. Thus my suspicion that this could be an interaction between usb and filesystem. OTOH, I can easily be totally wrong here. Feedback and / or requests to perform more debugging tasks are welcome.
