But I am not getting a core dump after panic. I have gone through the developers manual and I believe I have taken care of all the usual stuff. dumpdev="/dev/ad2s1b" dumpdir="/var/crash" savecore_flags="-v -z" hw.physmem: 508989440 Device 1K-blocks Used Avail Capacity /dev/ad2s1b 768000 0 768000 0% /dev/ad2s1d 989M 7.9M 902M 1% /var My kernel panics immediately on boot up, before the disks are probed. After panic I boot with a different kernel to extract the core. But I get the following error during boot up. Checking for core dump on /dev/ad2s1b... unable to open bounds file, using 0 checking for kernel dump on device /dev/ad2s1b mediasize = 786432000 sectorsize = 512 magic mismatch on last dump header on /dev/ad2s1b savecore: no dumps found >How-To-Repeat: This happens every time. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
