Hi Mark,

by now my second test-run was also succesful.

so it seems you were absolutely right. thank you very much for the hint.

that sounds just too weird ... but i see %)

argh.

i would like it to be understood that i (and probably many other people
like me) will come here, pester important developers, bind resources - and
generally lose faith in freebsd - without these options in GENERIC.

in fact, personally i would now say that the system without those options
should not be released as 5.1 - the trouble i've experienced shouldn't be
default in a freebsd release.

a nice workaround would be great, of course. assuming terry knows what
he's doing, i'm sure such code would be preferrable to turning on these
options by default. but until then, turning them on sounds like the safest
bet to me. i'd sacrifice some speed for reliability anyday. and so far i
felt that freebsd always had that philosophy.
