Not related at all. The 8535 is a regression caused by the Stuart's patch
to fix errors which happen when a CPU changes its speed. Stuart has updated
the patch since then, it sits in Greg's USB tree.

The -75 is a "babble", it usually means wrong request size or a bad DMA
  address, but in your case it was a PCI bandwidth starvation
The -71 is an "error", it usually means poor signal integrity due to
  cabling, but in this case it was EHCI switching the port
  during a transfer

You also hit an unrelated crash when sysfs did its use-after-kfree
excercise.
