This is a multi-part message in MIME format. --------------BAB93E71CE2D23CD7A63B8DF Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Hoi, does anyone have an idea how to solve the following problem: I have a dual Pentium 90 Intel SMP-1.1 compliant machine which runs fine in UP-mode (-stable (last time I tried -current gave exactly the same behaviour)); when I turn on SMP, it runs fine iff I turn down the network interface and any network related daemons. When turning on networking the system continues to function normally for a couple of minutes and then ``xl0; watchdog timeout'' messages start to show up. what is interesting is that jobs that have been started before (e.g. ``top'' (very practical)) continue to run at normal speed, whereas each job that has been started after the first ``xl0: watchdog timeout'' message, does not depass 1 or 2 percent CPU usage and ``top'' often mentions the ``vmwait''-state for them. BTW, using the ``lnc1'' ethernetdriver the above-mentionned behaviour is even more accentuated. Attached are my kernel-config file, dmesg -v output and mptabel output. Many thanx in advance.
