These messages might be harmless. The 3.0 kernel contains a fix for
Intel Panther Point xHCI hosts that suppresses those messages, commit
ad808333d8201d53075a11bc8dd83b81f3d68f0b "Intel xhci: Ignore spurious
successful event."
A later commit extends that to all xHCI 1.0 hosts, commit
07f3cb7c28bf3f4dd80bfb136cf45810c46ac474 "usb: host: xhci: Enable
XHCI_SPURIOUS_SUCCESS for all controllers with xhci 1.0" That was
queued for 3.11 and marked to be backported into stable kernels as old
as 3.0.
I see the same error message on the 0.96 ASMedia controller when
the rx buffers for the ax88179_178a driver cross 64k boundaries.
So this isn't confined to 1.0 controllers.
Sarah,
since there is no response yet, is there anyone at Intel dedicated at
working on USB 3.0?
We are also getting more and more negative USB 3.0 feedback with Linux
Still nobody appears to have provided the requested debugging
information that was requested. So there is not much that can be done
upstream to debug things based only on vague reports, especially when
not using current kernel versions.
