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
