savecore problem

Hello there. I've got a problem. Recently my personal server issued a
kernel panic. Then there's a dump and so on. But there's no dump
information after reboot. I do not know what was really the panic cause but
assume that savecore failed because of RAID.

Problem - minidump was done (I saw it was) but was not recovered by
savecore after reboot into /var/vrash

Think different.
Just superior.
