I have similar situation. My SMP machine runs fine with pre-PAE 4.8-STABLE and freezes with 4.9-STABLE quite often. There is no kernel panic, no crashdump. So I was forced to downgrade it to 4.8-STABLE of 8 August 2003 and keep it secure by applying patches. > I have the following: > > #/etc/rc.conf > #rebooting > dumpdev=YES > savecore=YES > dumpdir="/var/crash" > > I know ths is not quite enough - I need to configure a dump devide but I > have no tape drive. Is there another way? Yes. You should have swap partition greater or equal to size of RAM and enough free space in /var/crash (using symlinks is OK). And point dumpdev to your swap like this (example!): dumpdev=/dev/ad0s1b > > I rebuilt this kernel with: > > makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols > > Is there anything else I should do?

And even if I did > have physical access I am not sure how to do that exactly... It should not be necesary if you manage to get crashdump. Eugene Grosbein
