Package: linux-image-3.16.0-4-amd64 Version: 3.16.7-ckt11-1+deb8u3 Tags: ipv6
On a virtual machine running jessie (in a pretty default configuration, using systemd, etc.), I have an OpenVPN server configured like this: https://community.openvpn.net/openvpn/wiki/IPv6 I use "ip -6 neigh add proxy ..." statements to configure the IPv6 routed block used for assigning addresses to the VPN clients, with these rules in /etc/network/interfaces: iface eth0 inet6 static address xxxx:xxxx:xxxx:7::1 netmask 64 gateway fe80::1 up ip -6 neigh add proxy xxxx:xxxx:xxxx:8::1000 dev $IFACE up ip -6 neigh add proxy xxxx:xxxx:xxxx:8::1001 dev $IFACE up ip -6 neigh add proxy xxxx:xxxx:xxxx:8::1002 dev $IFACE down ip -6 neigh del proxy xxxx:xxxx:xxxx:8::1000 dev $IFACE down ip -6 neigh del proxy xxxx:xxxx:xxxx:8::1001 dev $IFACE down ip -6 neigh del proxy xxxx:xxxx:xxxx:8::1002 dev $IFACE (The "down ip ..." statements have no influence on the bug described here, the kernel panic happens also if they are removed.) This all works, until attempting a "shutdown -r" which causes the systemd shutdown process to proceed as expected all the way until it's supposed to execute "networking: Deconfiguring network interfaces..." but instead gets a kernel panic, logging the following in journalctl: Aug 11 03:55:31 xxxx kernel: INFO: rcu_sched self-detected stall on CPU { 3} (t=5250 jiffies g=555 c=554 q=243) Aug 11 03:55:31 xxxx kernel: sending NMI to all CPUs: Aug 11 03:55:31 xxxx kernel: NMI backtrace for cpu 3 Aug 11 03:55:31 xxxx kernel: CPU: 3 PID: 703 Comm: ip Not tainted 3.16.0-4-amd64 #1 Debian 3.16.7-ckt11-1+deb8u3 Aug 11 03:55:31 xxxx kernel: Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 Aug 11 03:55:31 xxxx kernel: task: ffff880036ca15f0 ti: ffff8800b9bd8000 task.ti: ffff8800b9bd8000 Aug 11 03:55:31 xxxx kernel: RIP: 0010:[<ffffffff8104b02e>] [<ffffffff8104b02e>] flat_send_IPI_mask+0x6e/0xa0 Aug 11 03:55:31 xxxx kernel: RSP: 0018:ffff8800bfb83e30 EFLAGS: 00010046 Aug 11 03:55:31 xxxx kernel: RAX: 0000000000000000 RBX: 0000000000000c00 RCX: 0000000000000006 Aug 11 03:55:31 xxxx kernel: RDX: 0000000000000c00 RSI: 0000000000000002 RDI: 0000000000000086 Aug 11 03:55:31 xxxx kernel: RBP: 000000000000000f R08: 000000000000000a R09: 0000000000000000 Aug 11 03:55:31 xxxx kernel: R10: 00000000000001a5 R11: ffff8800bfb83b96 R12: 0000000000000003 Aug 11 03:55:31 xxxx kernel: R13: ffffffff818e2940 R14: 00000000000000f3 R15: ffffffff81853680 Aug 11 03:55:31 xxxx kernel: FS: 00007f37d3cc1700(0000) GS:ffff8800bfb80000(0000) knlGS:0000000000000000 Aug 11 03:55:31 xxxx kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b Aug 11 03:55:31 xxxx kernel: CR2: 00007fffc1c7cfd0 CR3: 00000000b8ac0000 CR4: 00000000000006e0 Aug 11 03:55:31 xxxx kernel: Stack: Aug 11 03:55:31 xxxx kernel: 0000000200000008 0000000000000086 ffff8800bfb8d660 ffffffff81853680 Aug 11 03:55:31 xxxx kernel: ffffffff81046ab3 ffff8800bfb8d660 ffffffff810c53ca ffff8800bfb8dac0 Aug 11 03:55:31 xxxx kernel: ffffffff8109a04e ffff8800bfb92f00 ffff880036ca15f0 0000000000000000 Aug 11 03:55:31 xxxx kernel: Call Trace: Aug 11 03:55:31 xxxx kernel: <IRQ> Aug 11 03:55:31 xxxx kernel: Aug 11 03:55:31 xxxx kernel: [<ffffffff81046ab3>] ?
