Hello, I''ve been having an issue with a particular DomU on a server. The Dom0 runs other instances just fine, this particular instance will run just fine for a few hours to a few days, then it will just die out with the following error: --- kernel BUG at drivers/net/xen-netfront.c:305! invalid opcode: 0000 [#1] SMP Modules linked in: CPU 0 Pid: 0, comm: swapper/0 Not tainted 3.6.6-gentoo #1 RIP: e030:[<ffffffff812c14ad>] [<ffffffff812c14ad>] xennet_alloc_rx_buffers+0x1d7/0x2fe RSP: e02b:ffff88006da03d80 EFLAGS: 00010286 RAX: 00000000000001ff RBX: ffff880066f88000 RCX: 0000000000000001 RDX: 0000000000000057 RSI: 0000000000000000 RDI: 0000000000004fc0 RBP: 000000000cc1323f R08: 0000000000000000 R09: 00000000000038df R10: 00000000000004f1 R11: 0000000000003431 R12: 000000000cc13257 R13: ffff8800669c0600 R14: 00000000000004fc R15: 0000000000000057 FS: 00007fcb35820740(0000) GS:ffff88006da00000(0000) knlGS:0000000000000000 CS: e033 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 00007fcb3052e260 CR3: 000000005aa3a000 CR4: 0000000000042660 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process swapper/0 (pid: 0, threadinfo ffffffff81586000, task ffffffff81599410) Stack: 0000000000000056 0000001864b24900 ffff880066f89430 ffff880066f89c80 ffff880066f88000 0000000000000001 ffff880066f88758 ffff88006da18d30 ffff880066f88000 0000000000000000 ffff88006da03e28 ffffffff812c2a61 Call Trace: <IRQ> [<ffffffff812c2a61>] ? xennet_poll+0xa0a/0xa98 [<ffffffff8104e45d>] ? hrtimer_interrupt+0x112/0x1c9 [<ffffffff81326920>] ? net_rx_action+0x6e/0x139 [<ffffffff8103a91a>] ? __do_softirq+0x9c/0x145 [<ffffffff81281e9d>] ? __xen_evtchn_do_upcall+0x1b0/0x1ed [<ffffffff8141973c>] ? call_softirq+0x1c/0x30 [<ffffffff8100be36>] ? do_softirq+0x3c/0x7a [<ffffffff8103ab82>] ? irq_exit+0x42/0x9a [<ffffffff812838cb>] ? xen_evtchn_do_upcall+0x27/0x32 [<ffffffff8141978e>] ? xen_do_hypervisor_callback+0x1e/0x30 <EOI> [<ffffffff810013aa>] ? hypercall_page+0x3aa/0x1000 [<ffffffff810013aa>] ? hypercall_page+0x3aa/0x1000 [<ffffffff81006836>] ? xen_safe_halt+0xc/0x13 [<ffffffff81011003>] ? default_idle+0x23/0x3f [<ffffffff8101182c>] ? cpu_idle+0x60/0xa2 [<ffffffff8161baca>] ? start_kernel+0x32e/0x339 [<ffffffff8161b5b5>] ? repair_env_string+0x54/0x54 [<ffffffff8161e2b2>] ? xen_start_kernel+0x465/0x46b Code: 45 08 49 c7 45 08 00 00 00 00 48 89 42 08 48 89 10 41 0f b6 d7 49 89 5d 20 48 8d 82 a8 01 00 00 48 83 bc c3 40 07 00 00 00 74 02 <0f> 0b 48 8b 7c 24 18 4c 89 ac c3 40 07 00 00 48 89 14 24 e8 e2 RIP [<ffffffff812c14ad>] xennet_alloc_rx_buffers+0x1d7/0x2fe RSP <ffff88006da03d80> ---[ end trace 77f364e88037c131 ]--- Kernel panic - not syncing: Fatal exception in interrupt --- Here''s the config for that instance: kernel = "/xen/kernels/kernel-linux-3.6.11-domU" memory = 6144 maxmem = 16384 maxvcpus = 24 vcpus = 2 name = "REDACTED" disk = [''phy:/dev/vg/REDACTED-root,sda1,w'',''phy:/dev/swap/REDACTED-swap,sdb1,w''] root = "/dev/xvda1 ro" extra = "console=hvc0 xencons=tty" vif = [ ''bridge=eth0,mac=00:16:3e:52:ca:47'', ''bridge=eth1,mac=00:16:3e:d4:b7:d8'' ] It''s just a basic LAMP setup, with the MySQL being external to the instance.

Drop Xen-user, add Xen-devel Annie, this is the bug report I talked about. Have you encountered this before? Wei.
