Subject:   10.1-STABLE/i386 GENERIC + VIMAGE: Panic when going multiuser
Message-ID:  <20150103.180210.74719874.sthaug@nethelp.no>

next in thread | raw e-mail | index | archive | help
I have a reproducible crash in 10.1-STABLE/i386, svn updated to r276174.
The kernel is based on GENERIC with *one* line added: options VIMAGE.

I can boot to single user with no problem. Going multiuser results in
immediate crash with backtrace

The full core.txt.1 is included below. /var/crash/vmcore.1 is also
available if anybody is interested.

Is this a known problem? The server boots a GENERIC kernel built from
the same source code with no problems.
