Description James 2012-06-02 21:12:27 UTC
I have a Huawei e1550 mobile broadband dongle (which also doubles up as a virtual CD-ROM drive with drivers on it). My notebook has a NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04), running kernel 3.4. Shortly after attaching the modem to a USB 3.0 port, the following shows up in dmesg:


[28980.250828] usb 3-2: new high-speed USB device number 7 using xhci_hcd

[28981.309991] sd 33:0:0:0: [sdb] Attached SCSI removable disk


A short time afterwards the following appears:


[29065.953248] xhci_hcd 0000:03:00.0: ERROR Transfer event TRB DMA ptr not part of current TD
[29101.105619] xhci_hcd 0000:03:00.0: ERROR Transfer event TRB DMA ptr not part of current TD

[29123.207488] sr 32:0:0:0: rejecting I/O to offline device


The final line repeats indefinitely until the modem is unplugged. The modem otherwise appears to work. This doesn't happen when connected to a USB 2.0 port.
Comment 1 Sarah Sharp 2012-07-02 23:30:36 UTC
James, can you try compiling my for-usb-linus branch and see if this takes care of your issue?

git clone -b for-usb-linus git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci.g

There was a bug that got fixed that could cause the ERROR message to appear.

Hmm... every time I try that, I get "fatal: The remote end hung up unexpectedly". Are there some plain patches for 3.4.4 I could try?
Comment 3 Sarah Sharp 2012-07-24 21:26:52 UTC
James, can you retest with 3.4.5?  There was a patch that fixed the "ERROR Transfer event TRB DMA ptr not part of current TD" message for some other devices.  I suspect commit b62d32b9166b085a487916eca514b59b5ffdf2b7 may help your device as well.

I'm on 3.4.6 and I still get:


[107173.234727] xhci_hcd 0000:03:00.0: ERROR Transfer event TRB DMA ptr not part of current TD

Comment 5 Sarah Sharp 2012-07-25 19:53:16 UTC
Ok, James, thanks for trying that.  Can you recompile your kernel with CONFIG_USB_DEBUG and CONFIG_USB_XHCI_HCD_DEBUGGING turned on, and post the resulting dmesg with the failure.  I'll need to see some of the log before the failure as well.
Comment 6 Sarah Sharp 2012-07-25 19:54:11 UTC
Also, will you please post the output of `sudo lspci -vvv` and `sudo lspci -vvv -n`?  I need to see which host controller you're having issues with.

lspci outputs attached. Debug kernel will take a little longer, will post output in due course.
Comment 9 Sarah Sharp 2012-07-26 20:00:46 UTC
I think I have fixed the bug.  Please apply the attached patch and let me know if it fixes the ERROR messages.

Do you want the CONFIG_[..]_DEBUG options of Comment #5 enabled and the corresponding trace when built against this patch?

Yes.
Comment 13 James 2012-07-27 06:57:30 UTC
OK, I'll build a trace-enabled version soon. That said, things are looking good so far with the patch of Comment #10 applied (to a non-debug kernel).

A patch referencing this bug report has been merged in Linux v3.6-rc3:

commit 50d0206fcaea3e736f912fd5b00ec6233fb4ce44
Author: Sarah Sharp <sarah.a.sharp@linux.intel.com>

    xhci: Fix bug after deq ptr set to link TRB.
Comment 16 James 2012-09-06 20:55:36 UTC
For some reason, I'm now seeing this with the modem attached to a USB 2.0 port. I know it's appeared on at least kernel 3.5.2 with the patch from Comment #15, and on 3.5.3 (from my distro).
Comment 17 Sarah Sharp 2012-09-07 17:09:45 UTC
James: can you please open a separate bugzilla request?  It could be a different issue.
