Them manual page em(4) mentions trying another cable when the watchdog timeout happens, so I tried that. But it didn't help. Is there anything I can test to (help) debug this? It happens a lot when my machine is under load. (100% CPU) Is it possible that it happens since I upgraded the memory from 1GB to 2 GB? (dmesg was attached to my previous mail, but I can provide it again.) Ronald. -- Ronald Klop Amsterdam, The Netherlands
