--- Comment #43 from Mark Millard <markmi@dsl-only.net> ---
(In reply to Jeff Roberson from comment #42)

You may well be correct about unrelated bugs. But. . .

Looks like I Parse the 067613.html report differently
than you do:

A) First it says:

    Most recent CURRENT, as with r326363, crashes on booting the kernel

This is different than it later reports about -r326347 as I
parse the statements.

B) Then it says=20

    The last known half-ways good kernel is 12.0-CURRENT #157 r326347

Note the "half-ways" part. It then continues with what I
interpreted as a description of "half-ways" in a booted
-r326347 context (so, not for -r326363).

    When performing buildworld/buildkernel/relaese/package
    or poudriere on a ZFS filesystem, I can now bring down
    the system almost in a reproducible way.

I could be wrong but I do not see that as a report of the
"the last known good kernel".

--=20
