Hello Wilko, thanks a lot for the kind reply. I will go into more details below: On Tue, 8 Apr 2003, Wilko Bulte wrote: > > It run perfectly under FreeBSD 4.7 but unfortunately the kernel was no= t > > stable with having probably problems in memory so that I tried the 5.0= =2E > > Do you mean it reports Processor Correctable memory errors? How much memo= ry > does it have? The machine has about 1 GB RAM. Honestly I am not sure what "processor correctable memory errors" are, maybe it helps to show the output. That was from a selfcompiled kernel under 4.7 but I had the same problems when trying a generic.

This time I was using a generic kernel 5.0 with kldload-ed ipfw, but same problem before was on a self-compiled, why I changed back to the generic. Meanwhile I have compiled a kernel with suffiencet debug mode with the hope to offer proper error messages. > > > well as by any other reboot, the srm console gets into an desolate > > condition.

I think the "unalighed access error" when listing the firewall rules showed only up in the 5.0 version. I will probably downgrade to 4.7 or 4.8 (what is better to use?) again and recompile with ipfw2 then, and let you know then. Before I will try to produce proper errror messages with the debug kernel of 5.0. Maybe you can try out the SRM console problem without upgrading to 5.0 as I remember I first noticed it, when I booted from floppy or CD and called the machine to abort. I thought first of the errors reason to be my fault because of the abortion. Again 4.7 did not have that problem. thanks again and with best regards from Germany JR ---------------------------------------------------------------------------= -- Physikalische und Theoretische Chemie der TU-Braunschweig Jens R=F6der, Hans-Sommer Str.10, 38106 Braunschweig ---------------------------------------------------------------------------= --
