[Bug 1313279] [NEW] xHCI host not responding to stop endpoint command


You have been subscribed to a public bug:

Description:	Ubuntu 14.04 LTS
Release:	14.04
Hardware: Intel NUC D34010WYK (Core i3 4010U)
Memory: 4 gigabytes
USD device: PCTV 292e DVB-T tuner

I have 2 PCTV 292e DVB-T tuners connected to the system. When I start to
use either of the tuner, the xHCI host crashes. Since I'm booting from
an USB disk. If I only connect 1 of the tuners, the system works ok. It
does not matter which one of the tuners I connect.

[   68.990396] xhci_hcd 0000:00:14.0: xHCI host not responding to stop endpoint command.
[   68.990402] xhci_hcd 0000:00:14.0: Assuming host is dying, halting host.

Sometimes this also leads to this:

[  638.183002] IP: [<ffffffff815325dd>] usb_enable_link_state+0x2d/0x2f0
[  638.183057] PGD 0 
[  638.183077] Oops: 0000 [#1] SMP 

I can also observe the same fault with OpenELEC Linux distribution that
runs kernel 3.14 when I run the system from an internal SATA SSD drive
(not from an external USB disk).
