Subject: [V4.0.0-rc3] Xhci Regression: ERROR Transfer event TRB DMA ptr not part of current TD
Date: Tue, 10 Mar 2015 10:40:23 +0100	[thread overview]
Message-ID: <CADDKRnDPYxj8_iRd=S_Z4308v360nH41o24gHwB33TQsf-12mQ@mail.gmail.com> (raw)

If I plug in my USB DVB-T stick I get the following in dmesg:

dvb-usb: found a 'TerraTec/qanu USB2.0 Highspeed DVB-T Receiver' in warm state.
dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
DVB: registering new adapter (TerraTec/qanu USB2.0 Highspeed DVB-T Receiver)
usb 1-1: DVB: registering adapter 0 frontend 0 (TerraTec/qanu USB2.0
Highspeed DVB-T Receiver)...
input: IR-receiver inside an USB DVB receiver as
/devices/pci0000:00/0000:00:14.0/usb1/1-1/input/input17
dvb-usb: schedule remote query interval to 50 msecs.

dvb-usb: bulk message failed: -110 (2/0)

and DVB-T is not functional. The problem came in with:

1163d50 Merge tag 'usb-4.0-rc3' of
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

I never had this xhci_hcd error before so this is a regression.


Thanks, Jörg
