I had the opportunity to test 2 other nearly identical machines (one had a slightly lower clock rate than mine, both have other configurations of PCI cards and harddisks). The one with the lower clock rate run Lenny, the other an up-to-date Ubuntu 8.04 LTS. They run 4 days straight without any complications. So I guess my machine has a hardware problem and the Intel card maybe broken since memtest didn't detect any problems.
I suggest closing this bug. Regards, Martin -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
