I'm posting a slightly different patch for this issue. There are other commands which also had a 1 HZ timeout, where according to the InfiniHost/InfiniHost III PRMs the timeout should have been higher -- or different. All commands in the driver should have 60-second timeouts to be on the safe side, and the patch which follows corrects this oversight for INIT_HCA, CLOSE_HCA, SYS_EN, SYS_DIS, and CLOSE_IB. - Jack _______________________________________________ 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
