This is likely the same problem as the one I just posted about, but with 3.16 I get call traces and my USB bus came down and I couldn't even shut down the system. I've since gone back to my usual 3.13/Ubuntu kernel. Here's what happened. A snippet from dmesg is below, if anyone wants the whole thing, I've saved it. I just figured I'd report it! -- Evan Jul 22 23:58:26 Taro kernel: [ 9257.987466] CPU: 2 PID: 0 Comm: swapper/2 Not tainted 3.16.0-031600rc6-lowlatency #201407210035 Jul 22 23:58:26 Taro kernel: [ 9257.987471] Hardware name: Hewlett-Packard HP Pavilion TS 15 Notebook PC /216B, BIOS F.13 11/21/2013 Jul 22 23:58:26 Taro kernel: [ 9257.987476] 00000000000001f1 ffff88021ed03c98 ffffffff81789213 0000000000000007 Jul 22 23:58:26 Taro kernel: [ 9257.987485] 0000000000000000 ffff88021ed03cd8 ffffffff81071afc ffffffff815b6f00 Jul 22 23:58:26 Taro kernel: [ 9257.987493] ffff8800a9fe8000 ffff88021ed03d70 ffff8801ec91b680 00000001c5999000 Jul 22 23:58:26 Taro kernel: [ 9257.987501] Call Trace: Jul 22 23:58:26 Taro kernel: [ 9257.987506] <IRQ> [<ffffffff81789213>] dump_stack+0x4e/0x71 Jul 22 23:58:26 Taro kernel: [ 9257.987526] [<ffffffff81071afc>] warn_slowpath_common+0x8c/0xc0 Jul 22 23:58:26 Taro kernel: [ 9257.987535] [<ffffffff815b6f00>] ? trace_xhci_dbg_ring_expansion+0xa0/0xa0 Jul 22 23:58:26 Taro kernel: [ 9257.987542] [<ffffffff81071b4a>] warn_slowpath_null+0x1a/0x20 Jul 22 23:58:26 Taro kernel: [ 9257.987550] [<ffffffff815b8dd1>] xhci_find_new_dequeue_state+0x1b1/0x2e0 Jul 22 23:58:26 Taro kernel: [ 9257.987559] [<ffffffff815b9112>] xhci_handle_cmd_stop_ep.isra.42+0x122/0x2b0 Jul 22 23:58:26 Taro kernel: [ 9257.987568] [<ffffffff815ba596>] handle_cmd_completion+0x2d6/0x4a0 Jul 22 23:58:26 Taro kernel: [ 9257.987576] [<ffffffff815bbfee>] xhci_handle_event+0x1ae/0x2a0 Jul 22 23:58:26 Taro kernel: [ 9257.987584] [<ffffffff815bc200>] xhci_irq+0x120/0x1f0 Jul 22 23:58:26 Taro kernel: [ 9257.987592] [<ffffffff815bc2e1>] xhci_msi_irq+0x11/0x20 Jul 22 23:58:26 Taro kernel: [ 9257.987602] [<ffffffff810d0d7e>] handle_irq_event_percpu+0x3e/0x210 Jul 22 23:58:26 Taro kernel: [ 9257.987612] [<ffffffff810d0f98>] handle_irq_event+0x48/0x70 Jul 22 23:58:26 Taro kernel: [ 9257.987619] [<ffffffff810d3b17>] handle_edge_irq+0x77/0x110 Jul 22 23:58:26 Taro kernel: [ 9257.987626] [<ffffffff810187b2>] handle_irq+0x22/0x40 Jul 22 23:58:26 Taro kernel: [ 9257.987634] [<ffffffff8179901e>] do_IRQ+0x5e/0x110 Jul 22 23:58:26 Taro kernel: [ 9257.987642] [<ffffffff81796e2d>] common_interrupt+0x6d/0x6d Jul 22 23:58:26 Taro kernel: [ 9257.987645] <EOI> [<ffffffff810200d9>] ? sched_clock+0x9/0x10 Jul 22 23:58:26 Taro kernel: [ 9257.987661] [<ffffffff8161458e>] ? cpuidle_enter_state+0x5e/0xe0 Jul 22 23:58:26 Taro kernel: [ 9257.987668] [<ffffffff81614587>] ? cpuidle_enter_state+0x57/0xe0 Jul 22 23:58:26 Taro kernel: [ 9257.987676] [<ffffffff816146d7>] cpuidle_enter+0x17/0x20 Jul 22 23:58:26 Taro kernel: [ 9257.987684] [<ffffffff810baa19>] cpuidle_idle_call+0xe9/0x2c0 Jul 22 23:58:26 Taro kernel: [ 9257.987692] [<ffffffff810bae45>] cpu_idle_loop+0x255/0x270 Jul 22 23:58:26 Taro kernel: [ 9257.987701] [<ffffffff810baebb>] cpu_startup_entry+0x5b/0x60 Jul 22 23:58:26 Taro kernel: [ 9257.987708] [<ffffffff81048db5>] start_secondary+0xd5/0xe0 Jul 22 23:58:26 Taro kernel: [ 9257.987715] ---[ end trace b40b77c49a400b3d ]--- Jul 22 23:58:26 Taro kernel: [ 9257.987807] recv_control_msg() Failed receiving control message, error -110.
