The version of the I-pipe patch you are using has another known bug than the one fixed by the "arm: fix mm switching" patch (by the way, to be sure that we are talking about the same patch, I would prefer an URL pointing to xenomai's gitweb), the bug mentioned here: https://mail.gna.org/public/xenomai-core/2009-08/msg00021.html And the fix for this bug in the I-pipe patches which comes with Xenomai 2.4.10 should fix both bugs. So, in short, do you oberve the segmentation faults when using the I-pipe patches which ship with Xenomai 2.4.10 rather than whatever patch you are using for linux 2.6.26? -- Gilles. _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
