The machine paniced 17.46% of the way through (based on size of output). I disabled softupdates and was able to make world 3369 with no problems. (I did forget to put async and noatime back on for this but the build took only 2 hours 29 minutes - which is only 7 minutes slower than the build from 3345 to 3366 which had async and noatime on!! - It seems that async, noatime is not useful once you get reasonably fast drives - IBM 6.48 Million bytes Ultra DMA [but only running at mode 4] GMR heads - only 9.5ms ave seek but) Philippe Regnauld wrote: > > Kris Kennaway writes: > > > > a) The filesystem you're running softupdates on isnt mounted 'async' > > > > b) You're using the most recent version of the softupdates code from > > http://www.freebsd.org/~julian > > > > Since correcting the first problem, I've finished two 'make world -j8's > > without a hitch.
