Loading and unloading ib_mthca many times works fine on a non-Xen system. So there is something different about the Xen environment that is causing a problem. It could be a bug in mthca exposed by Xen (eg improper use of of the DMA mapping API or something like that). Can you turn on all the memory debugging options like SLAB_DEBUG etc. and see if it turns up anything? Also I'd be curious to see the exact XFS oops you're getting, since it might have a clue to what's going on. - R. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
