[issue840] panic without a panic message

[Rumko <sinknull@xxxxxxxxxxxxxxxxxxxxxxx>]

New submission from Rumko <rumcic@gmail.com>:

I was running many things (including trying to compile a lot of pkgsrc packages
inside a SMP vkernel) and the machine paniced. Since I was in X, I could not see
the panic message itself, but fortunately I got a dump.

The dump is available at leaf:~rumko/crash/dumps/*.0
