I have reinstalled and now starting from scratch to see if I can get the core dump of a panic. 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 Any idea? raj
