Hmm, quite a lot has changed between those two revisions, but I haven't heard of things breaking. Some things to try: - Build with CONFIG_INFINIBAND_MTHCA_DEBUG turned on, and see if there's anything enlightening in the kernel log. - Update your HCA FW to 4.7.400 -- it shouldn't matter but 4.6.0 has a lot of known bugs so it can't hurt. - Update to the latest svn rev, if you want to run svn drivers. Or you could try the stock drivers in 2.6.15.6. - Try passing the option "fw_cmd_doorbell=0" when loading ib_mthca. Again, it shouldn't matter but maybe it does. - Try a binary search of svn revisions between 3929 and 5685 to figure out when the driver stopped working. - R. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
