I'd be interested to see if this squashes the bug you have with your XBMC/NFS timing out. The error message will still be printed but should no longer break ethernet/etc.

I forced lots of spurious channel halts during testing and the USB system seemed to keep working.

dwc_otg: make channel halts with unknown state less damaging
b805851 
If the IRQ received a channel halt interrupt through the FIQ
with no other bits set, the IRQ would not release the host
channel and never complete the URB.

Add catchall handling to treat as a transaction error and retry.

mm/hotplug: fix hot remove failure in SPARSEMEM|!VMEMMAP case
d41e2f3 
In section_deactivate(), pfn_to_page() doesn't work any more after
ms->section_mem_map is resetting to NULL in SPARSEMEM|!VMEMMAP case.  It
causes a hot remove failure:
