Here's what I'm looking for in a good bug report (in no particular order): Stack backtrace if the kernel croaks. Ktrace if the kernel does something wrong. Elimination of unrelated factors. If you see the error compiling ports/x11/xorg, try to find out how little of it you can get away with doing to provoke the error ? If you are using complex disk geometries, try if you can reproduce on a plain single disk system ? Does it happen on other computers as well ? Does it happen only under SMP or also UP ? Does it happen also in single user mode ? Does enabling WITNESS/DIAGNOSTICS in the kernel catch something ? Can you write a shell script which fails every time ? Can you find another way to provoke it ? A patch. It is really very very simple, the easier you make it for me to reproduce the error here, the faster I can find out what's wrong and fix it. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
