:> Yes, all dev_t's which make it out of the kernel have cmajor

:> Try this change to savecore:

:Thanks, Poul.

A checklist for people who want kernel cores:
* make sure that dumpdev is set to point to your swap partition
in your /etc/rc.conf
* make sure your swap partition is large enough to hold the crash
dump. If you have 256MB of ram, your swap partition must be
at least 256MB in size.
* make sure /var/crash has sufficient space to hold the dump
(note: /var/crash *can* be a softlink to a directory in some
other partition if /var does not have sufficient space)
/var/crash must nominally have sufficient space to hold the crash
dump (a file of the same size as the amount of memory you have),
*and* the kernel image. Normally you give it a lot more space so
you store several crash dumps in it at once.
