--IS0zKkzwUGydFO0o Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hi, my very new kernel [1] makes my console freeze but I can still pings the box and even login with ssh. When I enter the debugger, the console "de-freezes" while in but as soon as I type "cont", it freezes again. I have noticed this problem two or three times for the last few days. My kernel configuration is attached. I would like to have some pointers to be able to provide some useful debugging informations. Note that it would be better if it can be done through ssh since I have no console cable, but if it's needed I will hand-write DDB output. Thanks. Best regards, [1] FreeBSD 6.0-CURRENT FreeBSD 6.0-CURRENT #57: Tue Feb 8 00:08:50 CET 2005 -- Jeremie Le Hen jeremie at le-hen dot org --IS0zKkzwUGydFO0o Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename=Z6PO #
