Andreas posted a release of his lil package on Aug 27. He notes that linux
shows periodic high interrupt latency due to large amount of time
(~15us) spent in the bottom handler processing in IRQ0.
I suppose, the latencies I see every 30-35 second period are due to the
same 'feature'. The linux bottom halfs and my interrupt run at slightly
different frequencies and they probably have an lcm of about 30-35
seconds, causing them to clash periodically. (IRQ0 wins ofcourse since its
highest priority)
I shall ofcourse do a lil more math to satisfy myself.. if anyone is
interested .. I can keep you posted.
