Scrolling through the syslog in a telnet session produces pauses every few seconds for about a second, that is while it's still responding. These problems seem to be network related, but there are no indications of what the problem is. This system also at times will just stop responding to network requests. 3) Both of the SMP systems are lacking the snappy responsiveness in X that I have become accustomed to with previous patches, but the 2.6GHz Xeon (w/HT) is worse than the 933MHz Xeon. Again no indications of problems in the logs. 4) Using amlat to run the RTC at 1kHz will kill any of these systems very quickly. kr - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
