Subject: Possible issue with tifm_7xx1 and interrupt latency

Although somewhat circumstancial, during the debugging of a FFADO issue with
a user it seemed possible that the tifm_7xx1 module may have been switching
interrupts off for long periods of time.  For a full history of the problem
please refer to

  http://subversion.ffado.org/ticket/250

Unfortunately the original reporter no longer has access to the hardware
concerned and the report itself dates from 2 years ago (I kept forgetting
to report it).  However, it may be useful none-the-less.

Please CC me any replies.

Thanks
  jonathan
