The file in this directory is a netboot kernel for IP32, R10K/R12K based systems. It should be regarded as extremely unstable, and WILL NOT BE SUPPORTED BY THE Gentoo/MIPS TEAM. So if you try it out, and it explodes, do not report the problem to us, as we know it doesn't work. It's here specifically for testing by people who know what they are doing, and simply as a proof of concept. That all said, try it out and let us know what you get. Update: 20060205 Some user feedback recommends the following options to be set in /proc immediately upon boot to further reduce the chances of triggering the speculative execution issue until the problem can be avoided: # Define length of time, in centisecs, between wakeups of pdflush echo 2 > /proc/sys/vm/dirty_writeback_centisecs # Set the minimum age of pages that pdflush will swap out echo 2 > /proc/sys/vm/dirty_expire_centisecs # Using swap space on disks controlled by the aic7xxx will lock up much faster echo 0 > /proc/sys/vm/swappiness
