debugging 15.0-RELEASE kernel on 15.0p3?

Hi,

I got my first kernel panic in ten years! (Was attempting to add a 32nd
zvol-backed drive to a bhyve guest.)

This host didn't have kernel debug symbols. I went to install them and
discovered my host needed updates. Thoughtlessly, I grabbed the new
kernel and the new symbols.

Oops. You can't debug a 15.0 kernel on 15.0p3.

bucket/var/crash;kgdb -n 0
kgdb: couldn't find a suitable kernel image

I have a 15.0 boot environment I could boot into, if there's a way to
install the debugging symbols? Or is there a way to pull the old
kernel and debug symbols down on the current BE?

On dch's advice I tried setting the pkg.conf URL:
  url:
"pkg+https://cloudfront.aws.pkgbase.freebsd.org/FreeBSD:15:amd64/base_release_
0/"
but got:
pkg: No SRV record found for the repo 'FreeBSD-base'


Thanks,
==ml

PS: I shoulda just done make world, that way I'd have /boot/kernel.old. ;-)
