Are you running JACK as root with "-R" or with "-R --asio"? Do these 50ms 
xruns occur even if you don't have any clients connected? If that's not 
the case, what client apps you have tested with? Also, do these xruns 
happen all by themself, or are you doing something at the same time (maybe 
moving windows or something). Does the HD led go on when the xrun occurs 
(kernel maybe syncing its caches)? What kernel, with low-latency patches, 
with pre-emption enabled or not?
