No, I haven't. (Secret Hacker Rule #11: Hackers read manuals. :-)
Really, I tried to do my best to find any mistake I made, especially
because I'm a new and unexperienced 'player' of -current, and so I read
the 'usual suspicious', where I found these hints to turn off debugging
code, compile with -DNO_WERROR and so on...
To be sure, I append my kernel config, but I would be surprised if
there's anything critical - maybe something unnecessary....
Anyway - thanks so far
Matthias
