Hi,
When I want to use my Behringer BCF2000 Ardour crashed with segmentationfault.
It only crashes when i'm using the mackie-protocol in Ardour
It crashes when I' moving the faders after couple of seconds.
I've run Ardour with strace, and i've got this message.
read(5, 0x1723924, 4096) = -1 EAGAIN (Resource temporarily unavailable)

Hi!
Could you rerun your crashing setup from gdb and provide us with a
backtrace?
In a terminal, go like this:
$ export GTK_PATH=/usr/lib/ardour2${GTK_PATH:+:$GTK_PATH}
$ export LD_LIBRARY_PATH=/usr/lib/ardour2${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}
$ gdb /usr/lib/ardour2/ardour-2.8.11
(gdb) run
When it crashes, say "thread apply all bt", that's the output we need.
If you cannot run ardour from gdb (it might have problems matching the
realtime deadlines), create a core instead:
$ ulimit -c unlimited
$ ardour2
[crash, should give you a file core.something in your CWD]
$ export GTK_PATH=/usr/lib/ardour2${GTK_PATH:+:$GTK_PATH}
$ export LD_LIBRARY_PATH=/usr/lib/ardour2${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}
$ gdb --core=XXX
(gdb) thread apply all bt
If this doesn't work, try the first method but start jackd without
realtime priorities.
TIA

while i cannot test the problem here, i wonder whether this is still an issue these days. Ardour has gone a long way since ardour2.8 (hey, we now have 5.5 in Debian/stretch). so maybe the problem has been magically resolved...
