I recently deployed the saucy kernel on that precise system, after the first reboot things looked fine but just a few minutes later, the whole system hang. I reproduced this very reliably 3-4 times, then hooked up a console cable and extracted the following kernel panic: [ 124.428031] ------------[ cut here ]------------ [ 124.432656] Kernel BUG at ffffffff81629ce8 [verbose debug info unavailable] [ 124.439622] invalid opcode: 0000 [#1] SMP [ 124.443766] Modules linked in: authenc(F) esp6(F) xfrm6_mode_transport(F) ipcomp6(F) xfrm6_tunnel(F) tunnel6(F) xfrm4_mode_tunnel(F) xfrm6_mode_tunnel(F) v) [ 124.577657] CPU: 0 PID: 12800 Comm: samba Tainted: GF WC 3.11.0-13-generic #20~precise2-Ubuntu [ 124.586962] Hardware name: /D2500CC, BIOS CCCDT10N.86A.0039.2013.0425.1625 04/25/2013 [ 124.596268] task: ffff8800cd711770 ti: ffff8800bfde2000 task.ti: ffff8800bfde2000 [ 124.603752] RIP: 0010:[<ffffffff81629ce8>] [<ffffffff81629ce8>] pskb_expand_head+0x288/0x2d0 [ 124.612305] RSP: 0018:ffff88012fc03688 EFLAGS: 00010202 [ 124.617621] RAX: 0000000000000003 RBX: ffff8800cd44d000 RCX: 0000000000000020 [ 124.624762] RDX: 0000000000000000 RSI: 0000000000000050 RDI: 00000000000006c0 [ 124.631900] RBP: ffff88012fc036c8 R08: 3f2c680500000060 R09: 3f2c680500000060 [ 124.639037] R10: bfcb2ffeff3e1602 R11: 20270ff0c0f20726 R12: 0000000000000050 [ 124.646175] R13: 0000000000000020 R14: 0000000000000001 R15: ffffffff81709280 [ 124.653317] FS: 00007f81c5448740(0000) GS:ffff88012fc00000(0000) knlGS:0000000000000000 [ 124.661407] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 124.667158] CR2: 000000000330e780 CR3: 00000000bfdc9000 CR4: 00000000000007f0 [ 124.674295] Stack: [ 124.676318] ffffe8ffffc00640 0000000180400040 ffff8801264d6d40 ffff8800cd44d000 [ 124.683792] ffff880126ddc000 ffff880126919180 0000000000000001 ffffffff81709280 [ 124.691262] ffff88012fc036f8 ffffffff816caac0 ffff8800cd44d000 0000000000000001 [ 124.698729] Call Trace: [ 124.701187] <IRQ> [ 124.703121] [<ffffffff81709280>] ?

None of the kernel traces above appear when running the original 3.2 kernel so for the time being, I've reverted to that kernel. This is a production firewall system so I can't easily make it accessible for debugging, but I'll be happy to do test runs for any debugging kernels you may provide.
