Hi, Kim. If you try to run 'lcrash' against /dev/vmdump as your
vmdump file ('lcrash -d /boot/System.map /dev/vmdump /boot/Kerntypes'),
what does it report?
Also, can you report what the output for:
dd if=/dev/hda8 bs=1 count=1000 skip=4096 | od -x
is? This will give a little more insight as to what's in the dump header.
