Log message:
Stop generating traffic for a given endpoint when a transfer reported
an I/O error.
When such thing happens, the device is more likely to be already gone
or non responding, but the task responsible for aborting the pipe has
not been executed.
Fix a problem where the ehci(4) controller would vomit^Wprint a lot of
"ehci_idone:" messages in loop leaving the machine unusable, initially
reported by ajacoutot@ and later by RD Thrush.
Fix tested by RD Thrush and Markus Bergkvist, thanks!
ok miod@
