I am surprised that it is the same bug. If I remember well, there were
two bugs:
- the first one was specific to NI 67xx cards and was fixed
- the second one was supposed to be fixed with the following commits:
analogy: [NI mite] initialize the mite structures after their allocations
analogy: [NI mite] initialize channels' status

I am afraid we are facing a bright new one...

Even if your system crashes, you might be able to catch the log traces
printed just before. In such a case, could you set the analogy debug
options like this:
CONFIG_XENO_DRIVERS_ANALOGY_DEBUG=y
CONFIG_XENO_DRIVERS_ANALOGY_DEBUG_LEVEL=0
CONFIG_XENO_DRIVERS_ANALOGY_DRIVER_DEBUG_LEVEL=1

And send your kernel traces, after having launched the attach procedure
(which, if I understand well, should have triggered the bug).
