In article <59063B5B4D98D311BC0D0001FA7E4522013137AD@l04.research.kpn.com> you write: >Hoi Jan Willem, > >I would tend to agree with Doug White about a "make world" being a good >memory test. However, I suspect Doug has the kind of system that will do a >make world in a minute or two. I too agree with Doug. It is what causes me to ask this question. ;-) make -j 4 buildworld keeps me getting crashes. Even during making the temp-tools. Now I've already replaced the memory once: 4*16M out, in 4*32M, but the crashingis still there. I've even set the timing to it's lowest, but still no go. I could go out an buy more new parts, but this is one of the cases to get to know FreeBSD again a little better. Memory testing skills are a leftover from a previous life. Heck, i've even help design a state-machine to test embeded RAM on VLSI ;-) >You should run "make world" to verify your test results, but if you've just >plopped in a new SIMM, making the world is just too heavy. > >> >> Any pointers to nightly reading material?? >> >Since FreeBSD systems will start pumping out random signal 11's in the face >of bad memory, try searching the -hardware and -questions list for that.

That's a nice idea a well, I think a module would learn me something more/new to do. But I'll also try and digout this program.
