BTW, I have been running xenomai 2.5 on ipipe 2.6.36 on p2020ds and
p2020rdb for several weeks now. Mostly, it seems stable. At least it
runs better than in that report. There are a few rough edges, but I
have not had the time to work on them or report them yet.

In any case, I suggest trying 2.6.36.



(Here is the exact version I have been using...)
