Welcome to the club ;-) Now, I'm no kernel expert either, but I wonder if you can reproduce your problem. If it's similar to mine, you should be able exactly what you did when the panic occured, and in about two out of three cases the problem should be there again. *Sigh*, Soren's fix has made my machine noticably more stable, what I really appreciate! However, there seem to be some issues that have not yet been sorted out, and the fact that these issues are there can only be blamed to VIA and the motherboard manufacturers (BIOS programmers). From what I can say, people who use their 686B machines for "normal" desktop work will probably never face this problem, even without any patching at all. On the other hand, people who are into (demanding) networking, compiling or file-copying will almost surely face this problem at some point in time, at least if their system is in the same state as Gavin's and mine is. If I had more money on my bank account right now, I'd probably simply replace my mainboard with an unaffected one (either no VIA chipset or one of the latest VIA things) and send my current one to Soren for further investigation. I guess that if he'd see how strange it performs, he'd throw it out of the window after a short period of time, and that's what I almost did for about 20 times so far ;-) Greetings Nils Greetings Nils -- Nils Holland Ti Systems - FreeBSD in Tiddische, Germany http://www.tisys.org * nils@tisys.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
