The problem with INVARIANTS is that 1. it alters data structures, 2. kernel modules don't know about this option, so you have inconsistent kernel and modules. There're three solutions, 1, make INVARIANTS less intrusive. So far only vm_zone code is causing problems, I suggest we rename the option to INVARIANTS_ZONE in this part of code (the code should be pretty much bug free by now). 2, compile modules with the option. The easiest way is probably add -DINVARIANTS in your /etc/make.conf, you have to remember to take it out when you remove the option from your config file. 3, do not use INVARIANTS if you don't need it. :) -lq To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
