I don't think OFED "supports" Xen, but it should work, and I would like to try to have at least the upstream kernel's mthca and other IB drivers work under Xen. I'm not sure what code is in OFED 1.3a exactly, but I don't see too many recent changes to mthca that look like they could cause your issue: > ib_mthca 0000:08:00.0: NOP command failed to generate interrupt (IRQ 16), > aborting. > ib_mthca 0000:08:00.0: BIOS or ACPI interrupt routing problem? > ib_mthca: probe of 0000:08:00.0 failed with error -16 Maybe the patch to try to enable MSI-X by default (which went in after 2.6.23 I think) is causing problems, although it looks like you are not on the MSI-X path. (Or were there other mthca messages too?) What kernel are you running in dom0? Is the change from OFED 1.2 to 1.3a the only difference between the working and non-working cases, or did you change anything else in your setup? - 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
