Assume that a reader of bugs@ has not seen your misc@ post. Include all
relevant information directly there including dmesg, details of the crash,
information about what you are doing, etc. Details of any other sysctl
changes you have made would be relevant too. Ideally you want to include
enough information that somebody else can recreate the problem, failing
that at least enough information that someone more familiar with the
internals can figure out what resulted in the conditions causing the
crash.
