I don't understand this claim. On what incredibly fast piece of iron can you possibly do between 8 and 16 kernel builds (the range I've encountered when I do the "git bisect" dance), boot each one, and evaluate the results in so small a period of time? An Alpha kernel build takes me between 5 and 10 minutes for minor changes, closer to four *hours* for a "from scratch" (make clean) build. Even worse: for those of us who don't have access to the console of the test machine continuously (e.g., the machine is at home and you normally work outside the home), the whole bisection process can take several days to complete. Yes, Mark's problem is with a laptop, and maybe he's allowed to take it with him into his workplace, but still... If your claim is 20 to 40 minutes "per iteration", I could believe that. -- ------------------------------------------------------------------------ Bob Tracy | "I was a beta tester for dirt.
