True, I know that. I did not send this in my email to you,
on which I never got an answer.
This time I submitted a problem report, to freebsd-bugs
in general, as I am not sure, that it could be an ATA problem
as well.
As far as I have looked at problem reports it is common, that
this information is included.
Please be assured, I did not ignore your instructions to hassle
you.
You have mentioned, that you need a valid backtrace, and I did know
that too. If you look closely at the problem report you will see,
that I have mentioned:

I am very sorry, that I did not get, that make installkernel
removes the symbols (although it says its not stripped!!),
before installing the kernel, but leaves a kernel.debug
file as well. Same seems to apply to the modules.
I will try to get both in place before the next crash.
I don't know which would be the right way to make
sure that the module contains the debugging symbols
as well for sure.
Here are the backtraces of the last three crashes now,
however they don't contain "vinum debug" in the calling
frame, so they might not be of use either.
